The grading system in Bangladesh has gone through significant changes over the past two decades. The current system uses two separate scales depending on the level: a 5.00-point scale for SSC and HSC, and a 4.00-point scale for most universities. Understanding how your percentage translates to a grade point — and how those grade points combine into a GPA or CGPA — is important for university admissions, scholarship applications, and job applications.
SSC and HSC: The 5.00-Point Scale
Secondary School Certificate (SSC) and Higher Secondary Certificate (HSC) results in Bangladesh use the National Curriculum and Textbook Board (NCTB) grade scale. Grades range from A+ (the highest) down to F (fail), with corresponding Grade Points on a 5.00 scale.
SSC/HSC Grade Scale (Bangladesh 5.00 Scale)
| Letter Grade | Marks Range (%) | Grade Point | Interpretation |
|---|---|---|---|
| A+ | 80 – 100 | 5.00 | Outstanding |
| A | 70 – 79 | 4.00 | Excellent |
| A− | 60 – 69 | 3.50 | Very Good |
| B | 50 – 59 | 3.00 | Good |
| C | 40 – 49 | 2.00 | Average |
| D | 33 – 39 | 1.00 | Poor |
| F | Below 33 | 0.00 | Fail |
How SSC/HSC GPA Is Calculated
The GPA for SSC or HSC is the average of the Grade Points across all subjects, including the optional subject if applicable. Some subjects are compulsory (Bangla, English, maths) and others are elective. The GPA is normally calculated to two decimal places.
GPA = Sum of all Grade Points / Total number of subjects Example: 6 subjects with grade points 5.00, 4.00, 5.00, 3.50, 5.00, 4.00 GPA = (5.00 + 4.00 + 5.00 + 3.50 + 5.00 + 4.00) / 6 = 26.50 / 6 = 4.42
University CGPA: The 4.00-Point Scale
Most universities in Bangladesh — including public universities under the University Grants Commission (UGC) and private universities — use a 4.00-point CGPA scale. The letter grades and cutoffs vary slightly between institutions, but the most widely used system is as follows.
Standard University Grade Scale (4.00 Scale — Most Common)
| Letter Grade | Marks Range (%) | Grade Point |
|---|---|---|
| A+ | 80 – 100 | 4.00 |
| A | 75 – 79 | 3.75 |
| A− | 70 – 74 | 3.50 |
| B+ | 65 – 69 | 3.25 |
| B | 60 – 64 | 3.00 |
| B− | 55 – 59 | 2.75 |
| C+ | 50 – 54 | 2.50 |
| C | 45 – 49 | 2.25 |
| D | 40 – 44 | 2.00 |
| F | Below 40 | 0.00 |
Note
Grade scales vary between institutions. BUET, BRAC University, North South University, and others may use slightly different mark ranges. Always check your institution's official academic regulations for the precise cutoffs.
Calculating CGPA Across Multiple Semesters
University CGPA is calculated as a credit-weighted average of all grade points earned. Each course has a credit value (typically 3 credits for a lecture course, 1.5 credits for a lab). The CGPA at any point is the sum of (Grade Point × Credit Hours) for every course, divided by total credit hours attempted.
CGPA = Σ (Grade Point × Credit Hours) / Σ Credit Hours Example: Two semesters Semester 1: Three 3-credit courses: A+(4.00), A(3.75), B+(3.25) → (12+11.25+9.75) = 33.00 / 9 credits = 3.67 GPA Semester 2: Three 3-credit courses: A(3.75), A−(3.50), A(3.75) → (11.25+10.50+11.25) = 33.00 / 9 credits = 3.67 GPA CGPA = (33.00 + 33.00) / (9 + 9) = 66.00 / 18 = 3.67
Tip
A failing grade (F) in most universities carries 0.00 grade points but the credit hours still count toward the denominator — so an F has a disproportionately large negative effect on your CGPA. Retaking and passing an F course replaces the grade in most institutions, but the F may still appear on the transcript with a note.
