Understanding IUB’s CGPA Grading System
The Independent University, Bangladesh (IUB) follows a 4.0 grading scale, similar to many universities worldwide. Your CGPA is calculated based on the grade points assigned to each course, considering its credit hours.
IUB CGPA Grading Scale
| Letter Grade | Score Range (%) | Grade Point (GP) |
|---|---|---|
| A | 90 – 100 | 4.0 |
| A- | 85 – 89 | 3.7 |
| B+ | 80 – 84 | 3.3 |
| B | 75 – 79 | 3.0 |
| B- | 70 – 74 | 2.7 |
| C+ | 65 – 69 | 2.3 |
| C | 60 – 64 | 2.0 |
| C- | 55 – 59 | 1.7 |
| D+ | 50 – 54 | 1.3 |
| D | 45 – 49 | 1.0 |
| F | Below 45 | 0.0 (Fail) |
Each grade corresponds to a grade point (GP), and your CGPA is the weighted average of these grade points across all courses.
How Credit Hours Affect Your CGPA
At IUB, each course carries a certain number of credit hours (or credit units). The higher the credit hours, the more impact that course has on your CGPA.
For example:
- Major/core courses → 3-4 credit hours
- General education courses → 2-3 credit hours
- Elective courses → 2-3 credit hours
If you perform well in high-credit-hour courses, your CGPA will improve faster than excelling in low-credit-hour courses.
Step-by-Step Guide: How to Manually Calculate Your CGPA
To manually calculate your CGPA at IUB, follow these steps:
Step 1: Convert Your Grades to Grade Points
Use the IUB grading scale above to assign grade points (GPs) to each course.
Step 2: Multiply Each Grade Point by the Course’s Credit Hours
For each course, multiply the Grade Point (GP) by the Credit Hours (CH). This gives you the Total Grade Points (TGP) for that course.
Step 3: Sum Up All the Total Grade Points
Add up all the Total Grade Points (TGP) from all courses.
Step 4: Divide by the Total Credit Hours (TCH)
Divide the Total Grade Points (TGP) by the Total Credit Hours (TCH) to get your CGPA.
Example of CGPA Calculation at IUB
| Course | Credit Hours (CH) | Grade | Grade Point (GP) | Total Grade Points (TGP) |
|---|---|---|---|---|
| ENG 101 | 3 | A | 4.0 | 3 × 4.0 = 12 |
| MAT 102 | 2 | B+ | 3.3 | 2 × 3.3 = 6.6 |
| CSC 103 | 3 | B | 3.0 | 3 × 3.0 = 9 |
| PHY 104 | 4 | A- | 3.7 | 4 × 3.7 = 14.8 |
| ECO 105 | 3 | C+ | 2.3 | 3 × 2.3 = 6.9 |
Final Calculation
- Total Grade Points (TGP) = 12 + 6.6 + 9 + 14.8 + 6.9 = 49.3
- Total Credit Hours (TCH) = 3 + 2 + 3 + 4 + 3 = 15
- CGPA = TGP ÷ TCH = 49.3 ÷ 15 = 3.29
📌 Final CGPA = 3.29
