If you study at Sylhet Agricultural University, you have probably typed “SAU grading system” or “how to calculate SAU CGPA” into Google at least once, and you have probably noticed something frustrating: there is no clear answer written for your university. You get generic CGPA calculators, admission circulars, and documents that belong to other universities. This guide fixes that. It explains the grading scale SAU Sylhet students work under, shows exactly how semester GPA and CGPA are calculated with real SAU courses, and is honest about the rules SAU has not published in a place students can easily find.
Quick answer: Sylhet Agricultural University (SAU Sylhet) is a public university under the University Grants Commission (UGC) of Bangladesh, and like other public universities it works on the national UGC 4.00 scale: A+ is 4.00 for 80 percent and above, A is 3.75, A- is 3.50, B+ is 3.25, B is 3.00, B- is 2.75, C+ is 2.50, C is 2.25, D is 2.00 for 40 to 44 percent, and anything below 40 percent is F at 0.00. Your semester GPA is the credit-weighted average of your grade points, and your CGPA is the same calculation stretched across every semester you have completed. One honest flag up front: SAU Sylhet does not publish its own grading ordinance in an easily searchable place on its official site, so the scale below is presented as the UGC national reference, and the SAU-specific rules on retakes, probation, graduation CGPA and F-grade treatment are marked UNVERIFIED in this guide, with the office you should confirm them with. Nothing in this guide is guessed and dressed up as an SAU rule.
Before anything else, check you are reading about the right SAU. Bangladesh has two universities with those initials. Sher-e-Bangla Agricultural University in Dhaka uses the domain sau.edu.bd. Sylhet Agricultural University in Sylhet uses sau.ac.bd. Search results mix them up constantly, and at least one directory on the web lists them as if they were the same institution. They are not. If a page you found talks about Dhaka campuses, Sher-e-Bangla, or a curriculum approved by a Dhaka academic council, it is not your university. This guide is about Sylhet only.
SAU Sylhet is a public agricultural university at Tilaghor, Sylhet. It started functioning on 2 November 2006 and now runs seven faculties with 47 departments, covering veterinary and animal sciences, agriculture, fisheries, agricultural economics and business studies, agricultural engineering and technology, and biotechnology and genetic engineering. Its best-known degrees are the Doctor of Veterinary Medicine (DVM), the B.Sc. in Agriculture (Hons.), and the B.Sc. in Fisheries (Hons.). The examples in this guide use real courses from SAU’s own DVM curriculum, so the credit loads and course names are not made up.
Check Your SAU GPA With the Calculator
The fastest way to check your number is to use the free calculator on the CGPAPro homepage. Add one row per course, pick the letter grade you received, enter the credit hours from your curriculum, and it returns your semester GPA instantly. Use the same tool semester after semester and you can track your CGPA as it moves. One honest caption: there is no dedicated SAU calculator page on the site, so the homepage calculator is the UGC-scale calculator, which matches the national reference scale explained in this guide. If SAU’s own published table ever differs from the UGC table for a particular course or session, your official transcript wins, not any online tool.
To use it correctly, you need two things from your own records: the credit hours of each course (your faculty curriculum lists them) and the letter grade on your grade sheet. Do not enter marks or percentages directly. Convert each total mark to a letter grade first using the table below, then enter the grade and the credit. A 1-credit practical course and a 3-credit theory course are not equal in the calculation, and that weighting is exactly where most hand calculations go wrong.
The Official Grading Table: The UGC National Reference
The University Grants Commission of Bangladesh recommended a uniform grading system for all public and private universities with effect from the 2006-2007 session, and public universities were directed to finalise results and issue transcripts under it. SAU Sylhet is a public university in that system. The table below is that national reference, and it is the table this guide uses for every worked example.
| Marks (percent) | Letter Grade | Grade Point | Standing |
|---|---|---|---|
| 80 and above | A+ | 4.00 | Outstanding |
| 75 to less than 80 | A | 3.75 | Excellent |
| 70 to less than 75 | A- | 3.50 | Very good |
| 65 to less than 70 | B+ | 3.25 | Good |
| 60 to less than 65 | B | 3.00 | Above average |
| 55 to less than 60 | B- | 2.75 | Average |
| 50 to less than 55 | C+ | 2.50 | Below average |
| 45 to less than 50 | C | 2.25 | Poor |
| 40 to less than 45 | D | 2.00 | Minimum pass |
| Less than 40 | F | 0.00 | Fail |
Two boundaries in this table catch students every semester. First, the bands are “less than” bands, not rounded bands: 79.6 percent is still an A, not an A+, and 74.9 percent is an A-, not an A. Marks are compiled in round figures, so a fractional total of 0.5 or above counts as the next whole number, but that rounding happens to the marks, not to the grade. Second, D is the minimum passing grade. A D earns you the credit. An F earns you nothing and, depending on the rule your faculty applies, may still sit in your GPA divisor, which is the trap explained in the worked examples below.
Do not confuse this 4.00 university scale with the 5.00 scale from your SSC and HSC days. School boards in Bangladesh grade out of 5.00, where A+ is 5.00 and the bands are completely different. SAU admission itself still talks in that language: the old admission circular required at least GPA 3.0 in SSC and at least GPA 3.0 in HSC, with a combined total of at least 6.5 without the fourth subject. Once you are inside the university, that scale is history. Everything from your first semester onward is out of 4.00.
How Your 100 Marks Are Built Up at SAU
Every SAU course, theory or practical, is evaluated out of 100 marks, and SAU’s own DVM curriculum spells out exactly where those 100 marks come from. This is verified SAU material, not a generic claim: attendance counts for 10 marks, midterm examinations count for 20 marks (two tests of 10 marks each), and the final examination counts for 70 marks. Theory courses and practical courses follow the same 10-20-70 split in the DVM curriculum.
That split has a practical consequence students underestimate. The final exam is 70 percent of your grade, but the other 30 percent is decided long before the final. A student who skips classes and midterm tests has already handed over up to 30 marks, which means the best final-exam performance in the world can only lift them to 70 out of 100, which is the bottom edge of A-. Attendance is not a formality at SAU. It is 10 percent of every course, and in a tight grade band it is often the difference between a B+ and an A-.
A note of caution: the 10-20-70 split is verified from the DVM curriculum. Other SAU faculties publish their own curricula, and while the university-wide pattern is similar, you should confirm the split in your own faculty’s curriculum document before assuming it applies to every course you take. Fisheries, agriculture and engineering curricula carry their own course structures, and practical-heavy courses sometimes weight components differently in practice.
Step-by-Step: Calculate Your Semester GPA
Calculating a semester GPA by hand takes about five minutes once you know the routine. Work through it in this order and you will not make the usual mistakes.
- List every course you took that semester, with its credit hours from your curriculum. Use the combined credit for a course, theory plus practical, exactly as your grade sheet lists it. A course listed as 2 theory plus 1 practical is a 3-credit course.
- Convert each course total mark to a letter grade using the table above. Remember the “less than” boundaries: 79 is A, 80 is A+.
- Convert each letter grade to its grade point. A+ becomes 4.00, A becomes 3.75, and so on down to F at 0.00.
- Multiply each grade point by that course’s credit hours. This gives the credit points for the course. A 3-credit A is worth 11.25 credit points; a 1-credit A is worth only 3.75.
- Add up all the credit points and add up all the credit hours separately.
- Divide total credit points by total credit hours. That is your semester GPA. Round to two decimal places, rounding half up.
The single most common error is step 4: students average their grade points without weighting by credits. A plain average of 4.00, 3.75, 3.00 and 2.00 is 3.19, but if the 4.00 course carried 1 credit and the 2.00 course carried 3 credits, the real weighted GPA is much lower. Credits are weights. Heavy courses pull harder in both directions.
The Formulas
For one semester, the formula is:
Semester GPA = (sum of grade point x credit hours for each course) / (total credit hours)
For your whole degree so far, there are two equivalent ways to get the same CGPA. The course-by-course way is identical to the semester formula, just stretched across every course you have ever taken. The semester way is easier once you have several semesters behind you:
CGPA = (sum of semester GPA x semester credit hours for each semester) / (total credit hours across all semesters)
Both routes give the same answer if you use unrounded semester GPAs inside the calculation. If you plug in GPAs already rounded to two decimals, your CGPA can drift by 0.01 from the official figure. That drift is harmless for planning, but if your result differs from your transcript by 0.01, rounding is the first suspect, not an error in your arithmetic.
Worked Example 1: A Real First Semester at SAU
Take a first-year, first-semester DVM student at SAU Sylhet. The curriculum gives this semester 17 credits in total. Here are the actual courses, their real credit loads, and a realistic set of grades:
| Course | Credits | Grade | Grade Point | Credit Points |
|---|---|---|---|---|
| ENG 101 Communicative English | 2 | A | 3.75 | 7.50 |
| RSC 101 Rural Sociology | 1 | B+ | 3.25 | 3.25 |
| FAS 101 Fundamental Animal Science | 2 | A- | 3.50 | 7.00 |
| GAN 101 Gross Anatomy-I | 3 | A | 3.75 | 11.25 |
| BHE 101 Basic Histology and Embryology | 3 | B | 3.00 | 9.00 |
| AHY 101 Animal Hygiene and Biosecurity | 2 | A+ | 4.00 | 8.00 |
| FPR 101 Fodder Production | 3 | B+ | 3.25 | 9.75 |
| COM 101 Computer Application | 1 | A | 3.75 | 3.75 |
Add the credit points: 7.50 + 3.25 + 7.00 + 11.25 + 9.00 + 8.00 + 9.75 + 3.75 = 59.50. Add the credits: 2 + 1 + 2 + 3 + 3 + 2 + 3 + 1 = 17. Divide: 59.50 / 17 = 3.50 exactly. This student’s first-semester GPA is 3.50.
Notice what carried this result. Gross Anatomy-I and Fodder Production are 3-credit courses, so together they contribute 21.00 of the 59.50 credit points, more than a third of the total. The 1-credit courses, Rural Sociology and Computer Application, barely move the number even with good grades. When you decide where to spend your revision time, spend it in proportion to credits, not in proportion to how many courses you have.
Worked Example 2: The F-Grade Denominator Trap
This is the example that matters most, because it is where SAU students get two different answers and both look correct. Consider a semester of 20 attempted credits with these results:
| Course (illustrative) | Credits | Grade | Grade Point | Credit Points |
|---|---|---|---|---|
| Course 1 | 3 | A+ | 4.00 | 12.00 |
| Course 2 | 3 | A | 3.75 | 11.25 |
| Course 3 | 3 | B+ | 3.25 | 9.75 |
| Course 4 | 3 | B | 3.00 | 9.00 |
| Course 5 | 3 | A- | 3.50 | 10.50 |
| Course 6 | 2 | C+ | 2.50 | 5.00 |
| Course 7 | 3 | F | 0.00 | 0.00 |
Total credit points: 12.00 + 11.25 + 9.75 + 9.00 + 10.50 + 5.00 + 0.00 = 57.50. Now watch what happens to the divisor.
If the F credits stay in the divisor (F counted): 57.50 / 20 = 2.875, which rounds to 2.88.
If the F credits are removed from the divisor (F excluded): 57.50 / 17 = 3.3823, which rounds to 3.38.
The same semester, the same grades, two answers half a grade point apart: 2.88 versus 3.38. That 0.50 swing can decide a scholarship, a merit position, or whether you look like a probation case. Some Bangladeshi universities count F credits in the divisor until the course is cleared; others exclude them. SAU Sylhet’s own rule on this point is UNVERIFIED in this research, which is exactly why this guide shows both versions instead of quietly picking one. If your transcript GPA matches the 2.88 version, your faculty counts F credits. If it matches 3.38, it excludes them. Check one real semester against your transcript and you will know your faculty’s rule for good. Until then, never quote a GPA that includes an F without saying which treatment you used.
The deeper lesson is not about the divisor. It is that one F in a 20-credit semester drags even a strong set of grades down hard. Without the F, this same student would have scored 57.50 / 17 = 3.38. With the F counted, they sit at 2.88. Clearing that F is the single highest-value academic move this student can make, worth far more than polishing a B+ into an A- somewhere else.
Worked Example 3: Can You Still Reach Your Target CGPA?
Students often ask whether a target CGPA is still reachable after a weak start. The honest answer is sometimes no, and it is better to learn that from arithmetic than from hope. The formula for the GPA you need from here on is:
Required future GPA = (target CGPA x total degree credits – current CGPA x completed credits) / remaining credits
Take a DVM student, since the DVM degree total is a verified 167 coursework credits (the 22 internship credits sit outside this calculation in the way the curriculum presents them, so confirm with your faculty whether internship credits enter your CGPA divisor). Suppose this student has completed 100 credits with a CGPA of 2.80. That is 280.00 credit points banked. They have 67 credits left, and they dream of graduating with a 3.50.
Target total points: 3.50 x 167 = 584.50. Points still needed: 584.50 – 280.00 = 304.50. Required average over the remaining 67 credits: 304.50 / 67 = 4.5447, which rounds to 4.54. The scale stops at 4.00. A 3.50 is mathematically impossible for this student, no matter how perfectly they perform from here. That is a painful answer, but it is a useful one: it stops wasted effort chasing an impossible number and frees the student to aim at a target that is real.
Now try a realistic target for the same student: graduating at 3.00. Required total points: 3.00 x 167 = 501.00. Points still needed: 501.00 – 280.00 = 221.00. Required average: 221.00 / 67 = 3.2985, which rounds to 3.30. That is demanding but achievable: roughly a B+ average, with A- grades in the heavy courses, across the remaining semesters. The gap between 3.30 and 4.54 is the gap between a plan and a fantasy, and the formula above is how you tell them apart in thirty seconds.
Run this calculation for yourself before every new semester. If the required average is above 4.00, reset the target. If it is between 3.50 and 4.00, you need near-perfect grades and should plan your semester load accordingly. If it is at or below your recent semester average, you are on track and your job is simply not to slip.
GPA vs CGPA: The Difference That Confuses Everyone
GPA, at SAU as elsewhere, usually means the result of one semester. CGPA means the cumulative result across all semesters completed so far. A semester GPA can jump around; the CGPA moves slowly, because every new semester is diluted by everything that came before it. That is why a brilliant final semester rarely rescues a weak CGPA on its own, and why one bad semester early does not ruin you either, provided the semesters after it are consistently good.
Here is a four-semester CGPA built from semester results, using the DVM credit loads from SAU’s curriculum:
| Semester | Credits | Semester GPA | Credit Points |
|---|---|---|---|
| Semester 1 | 17 | 3.50 | 59.50 |
| Semester 2 | 18 | 3.20 | 57.60 |
| Semester 3 | 20 | 3.40 | 68.00 |
| Semester 4 | 20 | 3.10 | 62.00 |
Total credit points: 59.50 + 57.60 + 68.00 + 62.00 = 247.10. Total credits: 17 + 18 + 20 + 20 = 75. CGPA: 247.10 / 75 = 3.2946, which rounds to 3.29. Note that the simple average of the four semester GPAs would be (3.50 + 3.20 + 3.40 + 3.10) / 4 = 3.30, which is close but not the same, because the semesters carry different credit loads. Always weight by credits. The simple average is only correct when every semester carries exactly the same number of credits.
One more distinction that trips up new students: your SSC and HSC GPA is not your CGPA, and employers and scholarship committees know the difference. A student who says “my GPA is 5.00” is talking about school results. A university CGPA of 3.29 out of 4.00 is a different scale entirely, and converting between them by any simple multiplication is meaningless. Keep the two scales in separate boxes in your head and on your CV.
Retakes, Probation, Graduation and Dean’s List: What Is Verified and What Is Not
This is the section where most online guides quietly invent rules. We will not. Here is the honest status of each rule for SAU Sylhet as of this research:
- Retake and improvement rules: UNVERIFIED. At many Bangladeshi universities, an F must be retaken and a passed course below a certain grade may be retaken for improvement, with the improved grade replacing the old one in the CGPA. Whether SAU Sylhet allows improvement retakes, which grades qualify, how many attempts are allowed, and whether the old grade stays visible on the transcript could not be confirmed from SAU’s published documents in this research. Do not assume the rules of BAU or Sher-e-Bangla apply to you.
- Probation rules: UNVERIFIED. The minimum semester GPA that keeps you in good standing, and what happens if you fall below it, could not be confirmed for SAU Sylhet. Other agricultural universities in Bangladesh commonly use a 2.00 semester GPA floor, but “commonly” is not “at SAU”, and this guide does not present it as an SAU rule.
- Graduation CGPA floor: UNVERIFIED. The minimum CGPA required to graduate could not be confirmed from SAU’s published documents. Many Bangladeshi universities set this at 2.00 or 2.50, but SAU Sylhet’s own figure must be confirmed.
- Dean’s List and merit positions: UNVERIFIED. The CGPA threshold for any Dean’s List, and how merit positions are awarded at graduation, could not be confirmed.
- F-grade treatment in the divisor: UNVERIFIED. Covered in worked example 2 above. Check your transcript against both calculations.
Where to confirm all of this: the Registrar’s office and the Controller of Examinations at Sylhet Agricultural University, through the official site at sau.ac.bd, or your faculty Dean’s office, which holds your faculty’s curriculum and ordinance documents. When you ask, ask for the specific document, not a verbal summary: “Which clause of the undergraduate ordinance covers retake of an F grade?” A clause number is something you can rely on. A corridor answer is not.
One practical tip while you wait for confirmation: keep your own spreadsheet of every course, credit, grade and grade point, updated each semester. If a rule is ever disputed, your own record, matched against your official grade sheets, is what lets you prove your number. Students who rely on memory lose these arguments.
SAU Degrees and Credit Loads
Understanding your degree’s total credits helps you plan, because the CGPA formula divides by total credits attempted. The DVM at SAU Sylhet totals 189 credits: 167 credits of coursework across eight semesters plus 22 internship credits. Semester loads in the DVM curriculum run from 17 credits in the first semester up to 25 credits in the fourth year, which means your later semesters carry more weight in your CGPA than your first ones. A strong fourth year counts more than a strong first year, credit for credit.
The B.Sc. in Fisheries (Hons.) is a four-year degree whose first semester alone carries 22.5 credits, with courses like Aquatic Zoology (FBG 111, 3 credits) and Fisheries Resources (ARM 111, 3 credits). The B.Sc. in Agriculture (Hons.) follows a similar four-year, eight-semester pattern through the Faculty of Agriculture, which has eleven departments including Agronomy and Haor Agriculture, Soil Science, Crop Botany and Tea Production Technology, and Genetics and Plant Breeding. If your degree is not DVM, pull your own faculty’s curriculum and note your semester credit totals before you calculate anything: a fisheries student’s 22.5-credit semester behaves very differently from a DVM student’s 17-credit first semester.
Students at other Bangladeshi science and technology universities face the same arithmetic, and the same honesty problem about unpublished rules. Readers comparing systems may find the guides for JUST, NSTU, HSTU and PSTU useful for seeing how the same UGC scale plays out under different faculty rules.
Common Mistakes SAU Students Make
- Averaging grade points without credits. A plain average treats a 1-credit practical and a 3-credit theory course as equals. They are not. Always multiply by credits first.
- Entering marks instead of grades into a calculator. A calculator that asks for grades wants letter grades. Entering 78 as if it were a grade point produces nonsense. Convert marks to grades first.
- Rounding at every step. Round only the final answer. Rounding each course’s credit points before adding them can shift your GPA by 0.01 or more.
- Forgetting the F in the divisor, or forgetting to remove it. As worked example 2 shows, this single choice swings the result by 0.50. Match one semester against your transcript to learn your faculty’s rule, then use it consistently.
- Mixing the 5.00 school scale with the 4.00 university scale. Your SSC/HSC GPA and your university CGPA live on different scales. Never average them together or convert one into the other for an official purpose.
- Ignoring attendance and midterm marks. At SAU, 30 of your 100 marks are decided before the final exam. Students who treat the final as the whole course start every course 30 marks behind.
- Trusting a page about the wrong SAU. If the page mentions Dhaka, Sher-e-Bangla, or sau.edu.bd, it is not Sylhet Agricultural University. Check the domain before you trust the rule.
- Assuming another university’s ordinance is yours. The widely shared “undergraduate ordinance” document circulating online belongs to Bangladesh Agricultural University in Mymensingh, not to SAU Sylhet. Its probation and repeat-exam clauses are BAU’s, and quoting them as SAU rules is how misinformation spreads.
Tips to Raise Your CGPA
Raising a CGPA is mostly a matter of arithmetic plus discipline, and the arithmetic tells you where effort pays best. First, protect the heavy courses. A one-step grade improvement in a 3-credit course is worth three times the same improvement in a 1-credit course. If you have limited revision time before finals, allocate it by credit weight, not by how worried you feel about each subject.
Second, bank the 30 marks that come before the final. Full attendance and both midterm tests are the cheapest marks in any SAU course, because they reward showing up and keeping pace rather than last-minute brilliance. A student who scores full attendance and midterm marks starts the final needing only 40 out of 70 to reach 70 overall, the A- boundary. A student who skipped them needs 70 out of 70 for the same grade, which is a much harder exam.
Third, clear F grades immediately. As the denominator example shows, one uncleared F can cost you 0.50 of GPA in a semester. No amount of polishing B grades elsewhere compensates for that. Find out your faculty’s retake window as early as possible and use the first available opportunity.
Fourth, plan with the required-average formula from worked example 3 at the start of every semester. Pick a target CGPA, compute the average you need across your remaining credits, and check whether that average is realistic given your recent performance. If it is not, adjust the target early instead of discovering the impossibility in your final year.
Fifth, treat practical courses seriously. At SAU, practical courses carry real credits, often 1 credit each, and there are many of them: a DVM semester can include seven practical credits. Students who focus only on theory and coast through practicals leak credit points all semester. A practical A is worth exactly as much per credit as a theory A.
Finally, verify your own numbers every semester. Compare your hand calculation with your official grade sheet. If they differ, find out why before the next semester starts: a divisor rule, a rounding difference, or a course you mis-credited. Errors compound silently across semesters, and final-year corrections are far harder than first-year ones.
Frequently Asked Questions
What grading scale does Sylhet Agricultural University use?
SAU Sylhet is a public university under the UGC, and the reference scale is the UGC national uniform 4.00 scale: A+ 4.00 for 80 percent and above, A 3.75, A- 3.50, B+ 3.25, B 3.00, B- 2.75, C+ 2.50, C 2.25, D 2.00 for 40 to 44 percent, and F 0.00 below 40 percent. SAU’s own published grading table was not found in an easily searchable place on sau.ac.bd during this research, so confirm the table against your faculty handbook or the Controller of Examinations if your grade sheet ever disagrees with it.
How do I calculate my SAU CGPA?
Multiply each course’s grade point by its credit hours, add up all those credit points, and divide by your total credit hours. For a semester GPA, use one semester’s courses. For CGPA, use every course you have completed, or equivalently weight each semester’s GPA by that semester’s credits and divide by total credits. The CGPAPro homepage calculator does this arithmetic for you once you enter grades and credits.
Does an F grade count in my CGPA at SAU?
This is UNVERIFIED for SAU Sylhet, and it matters more than almost any other rule: counting the F’s credits in the divisor versus excluding them can swing a semester GPA by 0.50, as worked example 2 demonstrates. Check one of your own semesters against your official transcript using both methods. Whichever version matches your transcript is your faculty’s rule. Until you have done that check, state which treatment you used whenever you quote a GPA that includes an F.
Can I retake a course to improve my grade at SAU?
UNVERIFIED for SAU Sylhet. Many Bangladeshi universities allow F courses to be retaken and sometimes allow improvement retakes of passed courses below a threshold grade, with the new grade replacing the old one. SAU Sylhet’s specific rules on eligibility, attempt limits, and transcript notation could not be confirmed from published documents in this research. Ask your faculty Dean’s office or the Controller of Examinations for the relevant ordinance clause, and confirm the retake window early, because retake opportunities are usually tied to the semester in which the course is next offered.
What CGPA do I need to graduate from SAU?
UNVERIFIED for SAU Sylhet. The minimum graduation CGPA could not be confirmed from SAU’s published documents. Do not rely on figures quoted for other universities, which commonly range from 2.00 to 2.50. Confirm your degree’s requirement with your faculty office in your first year, not your last, so you can plan around a real number.
Is SAU Sylhet the same as Sher-e-Bangla Agricultural University?
No. They are two separate public universities that happen to share the initials SAU. Sher-e-Bangla Agricultural University is in Dhaka (sau.edu.bd). Sylhet Agricultural University is in Sylhet (sau.ac.bd). Their curricula, ordinances and grading documents are different. Always check the domain and the city before trusting a document that claims to describe “SAU” rules.
How is the university CGPA different from my SSC and HSC GPA?
School results in Bangladesh use a 5.00 scale, where A+ is 5.00 and the grade bands are wider. University results use the 4.00 UGC scale described in this guide. The two numbers are not interchangeable, cannot be averaged together, and should never be converted by a simple multiplier for any official purpose. SAU admission requirements are still expressed in the school scale, which is why you will see GPA 3.0 and 6.5 figures in admission circulars, but everything after admission is out of 4.00.
Conclusion
Sylhet Agricultural University students have been working without a dedicated grading guide, piecing together generic calculators and documents from other universities. The core of the system is now clear: the UGC 4.00 scale, credit-weighted GPA and CGPA formulas, a 10-20-70 marks split in the DVM curriculum, and real credit loads you can check against your own curriculum. What remains unclear is also now clear in a different way: retake rules, probation, the graduation CGPA floor, Dean’s List thresholds and the F-grade divisor treatment are unpublished in any place this research could find, and this guide has marked each of them plainly instead of inventing answers. Take the verified arithmetic, use it every semester, confirm the unverified rules with the Registrar or Controller of Examinations through sau.ac.bd, and keep your own course-by-course record. Your CGPA is not a mystery. It is a weighted average, and now you can compute it, check it, and plan it yourself.
