Short answer: Southern University Bangladesh (SUB), the private university in Chittagong, does not publish its own grade table online — so the correct scale to use is the UGC Bangladesh uniform 4.0 scale (A+ = 4.00 at 80%+, down to F = 0.00 below 40%), the standard every UGC-affiliated private university is expected to follow. Your semester GPA is Σ (grade point × credit hours) ÷ Σ (credit hours), and your CGPA is the same formula stretched across every semester you have completed. Below: the full scale, two hand-checked worked examples (a 3.25 semester and a 3.39 two-semester CGPA), Southern’s actual 3-semester/2-semester structure, credit roadmaps, admission thresholds, the CGPA-linked tuition-waiver bands students always ask about — and an honest list of which Southern rules are confirmed and which you must check in your student handbook.
If you are a Southern student, read the next section first. The university’s own web address no longer leads where you think it does, and that confusion has sent a lot of students to the wrong documents.
First: Make Sure You’re Reading About the Right Southern
“Southern University” is one of the most ambiguous names in higher education. Before you trust any grade table or CGPA number, confirm you are looking at Southern University Bangladesh — the private university in Chittagong (Chattogram), Bangladesh, founded in 1998, with its permanent campus at Arefin Nagar, Baizid Bostami. These other institutions share the name and have nothing to do with your grades:
- Southern University and A&M College — Baton Rouge, Louisiana, USA. An American public HBCU. Its grading policy is irrelevant to you.
- University of the South (Sewanee) and Southern Adventist University — both American, both irrelevant.
- South University — an American for-profit system. Not yours either.
There is a second, subtler trap — and this one is Southern’s own. The domain southern.edu.bd, which used to be the university’s official website, now serves a site called “Southern Institutes” (contact info@southern.ac.bd), not the university’s academic pages. If you land there looking for your grade table, you will find nothing useful. Wikipedia currently lists southern.ac.bd as the university’s official site, and the legacy university site southernbd.net still carries official catalog content (programs, admission requirements, the university FAQ). Bookmark those two — not the repurposed .edu.bd domain.
Everything below is verified against Southern’s own published catalog pages (southernbd.net, its mirror sites, and the university’s program notices) — not against any American university’s handbook, and not against generic “Bangladesh CGPA” pages that never mention Southern at all.
Calculate Your Southern GPA the Easy Way
The fastest way to get an accurate number is the calculator below. Southern is a UGC-affiliated private university on the North-American-style semester system (credit hours, letter grades, Spring/Summer/Fall terms — the university’s own FAQ describes exactly this model), so select the “UGC Bangladesh” grade scale in the calculator: it carries the UGC uniform table (A+ 4.00 down to F 0.00) that Southern is expected to follow. Enter each course, its credit hours, and the letter grade you earned or expect, and the calculator does the credit-weighted math for you:
A filled example: five 3-credit BBA courses at Southern (B, B+, B, A, B+) producing a semester GPA of 3.25 on the UGC Bangladesh scale.
Quick start: type the course name, type the credit hours (Southern’s BBA courses are all 3 credit hours unless the course outline says otherwise), pick the letter grade from the dropdown, and add a row per course. The result updates as you go. The example above reproduces Worked Example 1 further down this page — try matching it to check your own entries.
One caution the screenshot doesn’t show: the calculator’s credit fields can look pre-filled while their actual value is still empty — always click into each credit box and type the number yourself, then confirm the result matches your hand calculation before trusting it.
Southern’s Grading Table: What You Should Use (and an Honest Caveat)
Here is the fact no other guide will tell you plainly: Southern University Bangladesh does not publish its official grade table online. We checked the university’s live domains, its legacy catalog, and its program pages on 20 October 2026 — no marks bands, no grade-point table. As a UGC-affiliated private university running the North-American semester model, Southern is expected to follow the UGC uniform 4.00 grading scale prescribed for Bangladeshi private universities (UGC Circular No. Sha/464/04/2690-100, dated 13.6.2006). Until Southern publishes its own table, use this — and confirm the bands against your current student handbook or your course outlines:
| Numerical Grade (Marks) | Letter Grade | Grade Point |
|---|---|---|
| 80% and above | A+ (A Plus) | 4.00 |
| 75% to less than 80% | A (A regular) | 3.75 |
| 70% to less than 75% | A− (A minus) | 3.50 |
| 65% to less than 70% | B+ (B Plus) | 3.25 |
| 60% to less than 65% | B (B regular) | 3.00 |
| 55% to less than 60% | B− (B minus) | 2.75 |
| 50% to less than 55% | C+ (C Plus) | 2.50 |
| 45% to less than 50% | C (C regular) | 2.25 |
| 40% to less than 45% | D (D regular) | 2.00 |
| Less than 40% | F (Fail) | 0.00 |
Three things worth noticing. First, do not confuse this with the NSU/BRAC-style scale that dominates Bangladeshi search results — those universities run a strict US-style table (A = 4.0, A− = 3.7). Southern’s scale gives you 3.75 for an A, not 3.7 — on a 15-credit semester, mixing the two scales shifts your GPA by more than a full letter grade on one course. Second, under this scale D (2.00, 40–44%) is the lowest passing grade and F is a fail — but Southern has not published which grades trigger probation or dismissal, so don’t assume. Third, because Southern’s own table is unpublished, this guide marks every Southern-specific policy as “confirmed” or “not published” in the ledger near the end — use that, not rumors.
How GPA Is Calculated at Southern — Step by Step
The university model Southern follows defines GPA the standard credit-weighted way. Follow these steps:
- Convert each letter grade to its grade point using the table above. A 72% in Microeconomics is an A−, worth 3.50 — not 3.7, not 3.67.
- Multiply each grade point by the course’s credit hours to get that course’s quality points. A 3-credit course with an A (3.75) contributes 3.75 × 3 = 11.25 quality points.
- Add up all quality points across the semester.
- Add up all credit hours attempted — including any F. A failed course contributes 0 quality points but its credits still sit in the denominator.
- Divide total quality points by total credits. That is your semester GPA.
CGPA uses the same formula across every semester you have completed: total quality points earned since enrollment divided by total credits attempted. Our SGPA formula guide with examples walks through the same credit-weighted logic with more practice cases.
The Formula
Semester GPA = Σ (Grade Point × Credit Hours) ÷ Σ (Credit Hours)
CGPA = Σ (Quality Points, all semesters) ÷ Σ (Credit Hours, all semesters)
Worked Example 1: A Southern BBA Semester (SGPA 3.25)
Take a typical five-course BBA semester — Southern’s BBA courses are 3 credit hours each, so 5 courses × 3 credits = 15 credits total:
| Course | Credits | Grade | Grade Point | Quality Points |
|---|---|---|---|---|
| Principles of Accounting | 3 | B | 3.00 | 3.00 × 3 = 9.00 |
| Microeconomics | 3 | B+ | 3.25 | 3.25 × 3 = 9.75 |
| Business Mathematics | 3 | B | 3.00 | 3.00 × 3 = 9.00 |
| English Composition | 3 | A | 3.75 | 3.75 × 3 = 11.25 |
| Computer Fundamentals | 3 | B+ | 3.25 | 3.25 × 3 = 9.75 |
| Total | 15 | 48.75 |
Adding the quality points: 9.00 + 9.75 + 9.00 + 11.25 + 9.75 = 48.75. Total credits: 15. Semester GPA = 48.75 ÷ 15 = 3.25 exactly. Notice how the single A anchors the average while the two B grades pin it down: without the A, this semester would have been 3.13; without the two B grades, it would have been 3.42.

Worked Example 2: Two Unequal Semesters → CGPA 3.39 (Not 3.40)
This is the example that catches students out, and it matters especially at Southern because (as you’ll see in the next section) different faculties run different numbers of semesters per year. Take a student with:
- Spring semester: 16 credits, semester GPA 3.20 → quality points = 16 × 3.20 = 51.20
- Summer semester: 14 credits, semester GPA 3.60 → quality points = 14 × 3.60 = 50.40
Total quality points = 51.20 + 50.40 = 101.60. Total credits = 16 + 14 = 30. CGPA = 101.60 ÷ 30 = 3.3866… = 3.39 (rounded to two decimals).
The trap: the naive answer is (3.20 + 3.60) ÷ 2 = 3.40 — and it is wrong, because the two semesters carried different credit loads. The 16-credit Spring semester pulls the average down harder than the 14-credit Summer semester pulls it up. Never average your semester GPAs directly. Always re-expand each semester as SGPA × credits, add the quality points, add the credits, and divide. (The naive average only works when every semester has identical credits — which is exactly what made Example 1’s single-semester case simple.)
GPA vs CGPA: Don’t Mix Them Up
Your semester GPA measures one term. Your CGPA measures your entire degree — it is the number on your transcript, the number employers and graduate schools ask for, and the number that determines your tuition-waiver tier. Because CGPA is cumulative, early semesters carry disproportionate weight: a rough first year over 30 credits needs a lot of 3.60+ semesters later to pull the average back up, since every new semester is diluted by the credits already banked.
The practical consequence: check your CGPA trajectory every semester, not just the term GPA. If the cumulative number is drifting below where you need it — a waiver cutoff, a transfer threshold of 2.50, a graduate-admission floor — that is the moment to act, not two semesters later. For the full breakdown of how the three measures relate, see CGPA vs GPA vs SGPA: the Difference Explained.
Southern’s Semester Structure — and What It Means for Your CGPA
Southern runs an unusual split that directly affects your CGPA math:
- Faculty of Business and Faculty of Arts, Social Science & Law: three semesters per academic year — Spring, Summer, and Fall.
- Faculty of Science & Engineering: two semesters per academic year — Spring and Fall.
This is official catalog content from the university’s program notices — and no generic CGPA guide mentions it, because they copy from each other instead of reading Southern’s pages.
Run the numbers. A Business student with a 2.80 first Spring over 15 credits who then posts 3.40 over 15 credits in Summer lands at (42.00 + 51.00) ÷ 30 = 3.10. An Engineering student with a 2.80 Spring over 18 credits who then posts 3.40 over 18 credits in Fall lands at exactly the same 3.10 — but the engineer had to wait a full semester longer to get the recovery term, and each term carried 18 credits of risk instead of 15. Same formula, different pacing. Plan your course loads accordingly: Southern defines full-time as 12 credit hours per semester with continuous enrollment across at least two semesters per year.

Program Credit Roadmaps: How Many Credits Your Degree Needs
Southern requires between 120 and 190 semester hours depending on the program (official catalog content). The headline numbers:
- BBA: 126 semester hours (36 general education + 72 core + 12 electives + 6 internship/project). All courses are 3 credit hours unless stated otherwise — so a BBA is 42 standard courses.
- MBA: 36 credit hours for business graduates, 60 for non-business graduates.
- EMBA: 39 credit hours across 3 semesters.
- BPharm, CSE, EEE, Civil, ECE, LLB, BA English: fall within the 120–190 range — confirm your exact total in your program’s curriculum sheet, since it’s the denominator your CGPA will live on.
Turn this into a pacing plan. At 12–15 credits per semester (the full-time band), a 126-credit BBA takes 8–10 semesters to clear. That’s 9–11 semesters for Business/Arts/Law students given the three-term year — meaning your CGPA is built from nearly a dozen individual GPA snapshots. One bad semester barely dents a 126-credit CGPA; three in a row do. That’s the real math behind “start strong.”
Admission and Transfer Rules (Confirmed from Southern’s Own Pages)
Southern’s admission floor is published and straightforward: undergraduate applicants need at least a second division or a minimum GPA of 2.5 out of 5.0 in both SSC and HSC (or equivalent via the Madrasha Board, or O/A-levels). All new applicants face an admission/evaluation test used for counseling and placement; the medium of instruction is English, and there is no distance learning — on-campus only.
Transfer students: you need a minimum 2.5 GPA from a recognized institution and good standing. Two rules govern how much of your old work counts:
- At least 45 semester hours (30 of them upper-division) must be completed at Southern itself to earn a Bachelor’s degree — you can’t transfer in the bulk of a degree.
- No more than 12 semester-hours transfer toward a Master’s. Quarter-hour credits convert at 1 semester credit = 1.5 quarter credits.
And here’s a contradiction we found in Southern’s own published pages, presented honestly: the university FAQ says only courses with at least a grade of “C” transfer; the Registration Information page says grades “less than C−” won’t transfer — which implies C− does transfer. When two official pages disagree, don’t guess: ask the admissions office exactly this — “If I earned a C− in a transferable course, will Southern accept it?” — and get the answer in writing.

Tuition Waivers: The CGPA Bands That Pay Real Money
This is the section Southern students search for most and find least. Southern ties tuition waivers directly to CGPA, in four bands:
| CGPA band | Tuition waiver |
|---|---|
| 3.00 – 3.25 | Up to 15% |
| 3.26 – 3.50 | Up to 20% |
| 3.51 – 3.75 | Up to 25% |
| 3.76 – 4.00 | Up to 30% |
These tiers come from a 2026 screen recording of the university’s official tuition page — treat them as the current published offer but confirm with the admissions office before budgeting, since fee schedules can change. Separately, an older official financial-assistance page describes academic scholarships for first-time freshmen requiring a 3.5 college GPA, renewable each year if the student maintains a 3.5 — that page reads as legacy policy, so the band table above is the better current guide.
Now connect the money to the math. Worked Example 1’s student sits at 3.25 — the top edge of the 15% band. How far is the 20% band? They need 3.26: that’s 3.26 × 15 = 48.90 quality points instead of 48.75 — just 0.15 quality points, i.e., one course moving up a single grade step anywhere (say the B in Business Mathematics becoming a B+ would add 0.75 quality points, landing at 49.50 ÷ 15 = 3.30). On a program costing roughly 377,520 BDT total (the BBA/HTM figure on the current fee page), the 5-percentage-point waiver difference is real money. This is the most useful arithmetic in the whole guide: compute the quality-point gap to your next waiver band before every semester, because a concrete number (“I need 0.75 more quality points”) turns vague “study harder” into a target you can plan around.
What Southern Confirms — and What It Doesn’t (Read This Honestly)
Most grading guides pretend everything is known. Here’s the honest ledger for Southern University Bangladesh as of October 2026:
| Rule | Status |
|---|---|
| Official grade table (marks bands + grade points) | Not published online — use the UGC uniform scale above, confirm with your handbook |
| Minimum passing grade | Not published by Southern — D (2.00) is the UGC-scale standard; verify |
| Retake / re-sit rule | Not published by Southern — verify; do not assume the old grade disappears from your CGPA |
| Probation and dismissal CGPA ladder | Not published by Southern — verify with your advisor or the Registrar |
| Dean’s List / honors criteria | Not published by Southern |
| Graduation minimum CGPA | Not published by Southern — the national norm is 2.00, but do not treat that as Southern’s rule |
| 3-semester vs 2-semester academic year | Confirmed — Business/Arts/Law: Spring, Summer, Fall; Science & Engineering: Spring, Fall |
| Degree credit totals (120–190 hrs; BBA 126) | Confirmed — program notices |
| Full-time = 12 credit hours/semester | Confirmed — registration requirements |
| Admission: SSC+HSC ≥ 2.5 GPA | Confirmed — registration requirements |
| Transfer: 2.5 GPA + C-vs-C− rule | Confirmed — two official pages, with the C/C− contradiction noted above |
| CGPA-linked tuition waivers | Published 2026 — official tuition page (screen recording); confirm before budgeting |
The “not published” rows are not a flaw in this guide — they’re the point. We checked where Southern’s own site goes dark so you know exactly which questions to take to your advisor or the Registrar, instead of trusting another university’s handbook that happens to look similar. For context on how probation and Dean’s-list thresholds generally work across the region, see Dean’s List & Academic Probation: CGPA Thresholds.
Common Mistakes Southern Students Make
- Using the NSU/BRAC-style grade table. The most common error in Chittagong search results. Those universities use a strict American scale (A = 4.0, A− = 3.7). On Southern’s expected UGC scale, an A is 3.75 — mix them up and your calculated GPA will be wrong.
- Averaging semester GPAs instead of credit-weighting them. (3.20 + 3.60) ÷ 2 = 3.40 looks right and is wrong whenever semesters carry different credits. Re-expand each semester as SGPA × credits, as Worked Example 2 shows.
- Forgetting that F credits still count. A failed 3-credit course adds 0 quality points but 3 credits to the denominator — it drags the GPA down twice as hard as you might expect.
- Ignoring the waiver-band edges. Students celebrate a 3.25 without noticing the 20% band starts at 3.26. One grade step can be worth real tuition money.
- Assuming a retake erases the old grade. Southern hasn’t published its retake rule. Some universities replace the grade in the CGPA computation; others average both attempts. Verify before you plan around it.
- Treating all credits equally. A 6-credit internship or project moves your CGPA twice as much per grade point as a 3-credit course. Weight your effort accordingly.
- Chasing southern.edu.bd for official documents. That domain is no longer the university’s academic site. Use southern.ac.bd (current, per Wikipedia) or southernbd.net (legacy catalog) instead.
Tips for Raising Your CGPA at Southern
- Price the gap to your next waiver band. Multiply the target CGPA by your total credits, subtract your current quality points — that’s the quality-point gap you need to close. A concrete number beats vague “study harder.”
- Attack high-credit, low-grade courses first. Quality points scale with credits — improving a 3-credit B to an A gains 2.25 quality points, more than polishing an already-strong grade.
- Use the Summer semester deliberately (Business/Arts/Law). Three terms a year is a recovery advantage: a focused Summer with 2–3 courses lets you add fresh quality points without the full-semester load.
- Protect the 40% line. Under the UGC scale, 39% is an F (0.00) and 40% is a D (2.00). A single mark at the boundary is worth 2.00 grade points — never leave a borderline course unaddressed.
- Model before you register. Run the before/after arithmetic (Worked Example 2) for every decision — adding a course, dropping to part-time, or retaking. The math tells you which move actually moves the CGPA.
- Document transfer-credit answers. Given the C-vs-C− contradiction on Southern’s own pages, get any transfer ruling in writing from admissions before you count on those credits.
Frequently Asked Questions
Which grading scale does Southern University Bangladesh actually use?
Southern does not publish its own grade table online. As a UGC-affiliated private university on the North-American semester model, it is expected to follow the UGC Bangladesh uniform 4.00 scale (A+ 4.00 at 80%+, down to F 0.00 below 40%) — the table reproduced in this guide. It is not the strict NSU/BRAC-style American scale (A− 3.7) that dominates Bangladeshi search results. Confirm the bands against your current student handbook.
Do Summer semesters count toward my CGPA at Southern?
Yes — for Business and Arts/Law students, Summer is a full regular semester (Spring, Summer, Fall), and its grades count toward your CGPA exactly like any other term. For Science & Engineering students there is no Summer semester; the academic year is Spring and Fall only.
What CGPA do I need for a tuition waiver at Southern?
Per the university’s 2026 tuition page: 3.00–3.25 earns up to 15% off, 3.26–3.50 up to 20%, 3.51–3.75 up to 25%, and 3.76–4.00 up to 30%. Confirm with the admissions office before budgeting, since fee schedules can change.
If I fail or get a bad grade, can I retake the course?
Southern has not published a retake policy online, so we won’t invent one. The national pattern at Bangladeshi private universities varies — some replace the old grade in the CGPA, others average both attempts. Ask your advisor or the Registrar for Southern’s actual rule before you plan a retake.
What is the minimum grade to pass at Southern?
Under the UGC uniform scale Southern is expected to follow, D (2.00, 40–44%) is the lowest passing grade and F (below 40%) is a fail. However, Southern has not published its own passing-grade rule, so verify against your student handbook or course outlines.
How many credits do I need for full-time status?
12 credit hours per semester, with continuous enrollment across at least two semesters per academic year, per Southern’s registration requirements.
Will my transfer credits count, and at what grade?
Transfer students need a 2.5 GPA and good standing, and at least 45 semester hours (30 upper-division) must be completed at Southern for a Bachelor’s. On the grade question, Southern’s own pages contradict each other — one says “C or better,” the other “not less than C−.” Get the ruling in writing from admissions for your specific courses.
Conclusion
Southern University Bangladesh’s grading system is straightforward once you anchor it to the right sources: the UGC uniform 4.0 table, credit-weighted exactly like the formula and examples above. The details that actually move your numbers are the Southern-specific ones — the three-term year for Business/Arts/Law versus the two-term engineering calendar, the BBA’s 126-credit denominator, the 12-credit full-time floor, and the waiver bands that turn 0.15 quality points into a tuition cut. And the rule this guide refuses to break: where Southern hasn’t published a policy — the retake rule, the probation ladder, the Dean’s List, the graduation floor — we say so, and we tell you exactly who to ask. Run your numbers through the CGPA calculator on the “UGC Bangladesh” scale, model your semesters before you register, and keep one eye on the next waiver band. That 3.26 is closer than it looks.
