How to Calculate NU Honours CGPA?
To calculate your Honours CGPA for National University (NU), you must convert each subject's marks into a Grade Point (using the 4.00 scale), multiply it by the Course Credit, and sum the results. Finally, divide the Total Quality Points by the Total Credits.
For example, if you obtained 65 marks (Grade B+, GP 3.25) in a 4-credit course, your Quality Point is 13.00. Do this for all courses to find your Semester or Yearly GPA.

| 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 |

How to Calculate CGPA for Honours Zoology (and others)
Many science students (like Zoology or Physics majors) struggle with calculating practical marks. In the NU system:
- Theory + Practical: Your theory and practical marks are often combined on the marksheet. Enter the Total Obtained Mark (out of 100) into the calculator.
- Credits Matter: A 4-credit major course impacts your CGPA twice as much as a 2-credit non-major course. Always check your syllabus for the correct credit hours (usually 4, 3, or 2).
CGPA Calculation Steps (Manual Method)
If you wish to calculate manually:
- Convert Marks: Use the table above to find the Grade Point (GP) for every subject.
- Calculate Quality Points: Multiply the GP of each subject by its Credit Hours.
(Example: GP 3.00 × 4 Credit = 12.00 Quality Points) - Sum it Up: Add all Quality Points together. Also, add all Credit Hours together.
- Divide: Total Quality Points / Total Credits = Final CGPA.
What Is a Good CGPA in Honours?
Understanding your standing is crucial for career planning.
- 3.75 – 4.00 (Excellent): Rare in NU. High chance for University Teaching jobs.
- 3.50 – 3.74 (Very Good): Strong profile for BCS cadre, Bank jobs, and scholarships abroad.
- 3.00 – 3.49 (Good): A safe "First Class" equivalent range. Eligible for almost all Govt. and Private jobs.
- 2.50 – 2.99 (Average): You may face competition but are eligible for Masters.
- Below 2.50: Needs drastic improvement. Retake courses if possible.
Common Mistakes to Avoid
Students often fail to get accurate results because:
- They simply average the Grade Points (Wrong! You must weight them by credits).
- They ignore the difference between 3-credit and 4-credit courses.
- They mistakenly enter 0 marks for Absent courses instead of removing the course credit (resulting in a fail calculation).
