What Is CGPA?
- CGPA means Cumulative Grade Point Average, the overall average of grade points across all completed subjects/terms.
- Most Bangladesh universities use a 4.00 scale.
National University (NU) Grading System
- 80+ = A+ (4.00), 75-79 = A (3.75), 70-74 = A- (3.50), 65-69 = B+ (3.25), 60-64 = B (3.00).
- 55-59 = B- (2.75), 50-54 = C+ (2.50), 45-49 = C (2.25), 40-44 = D (2.00), below 40 = F (0.00).
CGPA Formula for NU Honours (Credit Based)
- CGPA = Sum of (Grade Point × Credit) / Sum of Credits.
- This is a weighted average formula, so higher credit subjects impact final CGPA more.
CGPA Formula for NU Degree Pass
- CGPA = Total Grade Points / Total Number of Papers.
- This method uses equal weight per paper.
General University Formula
- Most public and private universities use: CGPA = Sum of (Grade Point × Credit Hours) / Total Credit Hours.
- Semester GPA is calculated similarly for each semester, and CGPA combines all semesters.
Step-by-Step Example (Weighted)
- Subject 1: 4 credits, GP 3.75 => 15.00
- Subject 2: 4 credits, GP 3.50 => 14.00
- Subject 3: 4 credits, GP 4.00 => 16.00
- Total points 45, total credits 12, CGPA = 45 / 12 = 3.75.
CGPA vs GPA
- GPA is typically for one semester/term.
- CGPA is the cumulative result across all semesters/years.
NU Classifications
- 3.50+ = First Class.
- 3.00-3.49 = Second Class.
- 2.50-2.99 = Third Class.
Common Mistakes in CGPA Calculation
- Ignoring credit hours in honours/credit-based systems.
- Using simple average where weighted formula is required.
- Mixing GPA and CGPA logic.
- Not including all subjects and cleared retake subjects properly.
