Honours CGPA Calculator (NU) 2026
Accurate Semester & Yearly CGPA Calculator for National University Bangladesh
✨ How to Calculate NU Honours CGPA?
Calculating your Honours Cumulative Grade Point Average (CGPA) under National University (NU) requires converting your obtained marks out of 100 into Grade Points on a 4.00 scale. You then multiply these points by the course credits to generate "Quality Points".
For example, if you obtain 66 marks (Grade B+, GP 3.25) in a 4-credit major course, your earned Quality Points equal 13.00. To find your final CGPA, input all your course marks and credits below.

Mastering the National University Honours Grading System in 2026
National University (NU) Bangladesh caters to the largest student population in the country. Hundreds of thousands of students enroll annually in 4-year Honours programs spanning disciplines like Zoology, English, Accounting, Political Science, and the BBA Professional program. While the curriculum is vast and diverse, the grading system is entirely centralized.
Calculating your CGPA under the NU system can be notoriously confusing. The official marksheet provides your raw marks (e.g., 62 out of 100), but postgraduate admissions, BCS circulars, and private sector employers exclusively demand your CGPA on a 4.00 scale. Furthermore, failing to account for the varying credit weights of major vs. non-major courses can result in completely inaccurate self-assessments.
This Honours CGPA Calculator is meticulously programmed with the latest 2026 National University grading rubric. This comprehensive guide explains the exact mathematical formula, how to handle in-course and practical marks, and what thresholds you need to cross to secure a 1st Class degree.
The Official NU Honours Grading Scale (4.00 Scale)
Under the UGC directive, National University transitioned from the traditional "Class System" (1st Division, 2nd Division) to the standardized 4.00 CGPA grading scale. Your raw marks out of 100 map directly to specific Grade Points and Letter Grades.
| Total Marks Obtained (%) | Letter Grade | Grade Point (GP) | Academic Meaning |
|---|---|---|---|
| 80% – 100% | A+ (A Plus) | 4.00 | Outstanding |
| 75% – 79% | A (A Regular) | 3.75 | Excellent |
| 70% – 74% | A- (A Minus) | 3.50 | Very Good |
| 65% – 69% | B+ (B Plus) | 3.25 | Good |
| 60% – 64% | B (B Regular) | 3.00 | Satisfactory |
| 55% – 59% | B- (B Minus) | 2.75 | Above Average |
| 50% – 54% | C+ (C Plus) | 2.50 | Average |
| 45% – 49% | C (C Regular) | 2.25 | Below Average |
| 40% – 44% | D (D Regular) | 2.00 | Passing Grade |
| 00% – 39% | F | 0.00 | Fail |
The 40% Pass Mark Rule: At National University, the minimum passing mark for any Honours course is 40%. If you score 39 marks or below, you earn an 'F' grade (0.00 Grade Points). This forces you to apply for an "Improvement" or "Retake" exam in the following academic year.
What is a "1st Class" CGPA in Honours?
Even though transcripts display CGPA, the Bangladesh job market—particularly the Bangladesh Civil Service (BCS) and government banking sectors—still strictly evaluates candidates based on the legacy class system. Based on official NU equivalency tables, here is how your CGPA converts:
1st Class Equivalent
CGPA 3.00 to 4.00Securing 60% marks (B Grade) or above on average. Highly recommended for BCS applicants and teaching professions.
2nd Class Equivalent
CGPA 2.25 to 2.99Securing 45% to 59% marks. Acceptable for most corporate jobs, but limits high-tier government quotas.
3rd Class Equivalent
CGPA 2.00 to 2.24Securing 40% to 44% marks. Generally makes a candidate ineligible for competitive government recruitment.
How the Honours CGPA Formula Mathematically Works
A common mistake National University students make is taking a simple average of their Grade Points. (e.g., "I got a 3.00, a 3.50, and a 4.00, so my CGPA is 3.50"). This is mathematically incorrect. Your Honours syllabus is built on a credit system.
Understanding Credit Hours
Major departmental subjects (like Advanced Accounting or Quantum Mechanics) are usually 4-Credit courses, representing 100 marks. Non-major subjects (like History of Emergence of Independent Bangladesh) or Practical Labs might be 2-Credit or 3-Credit courses (representing 50 or 75 marks). A 4-credit course impacts your final CGPA twice as heavily as a 2-credit course.
The Calculation Steps
- Convert your raw marks to a Grade Point (GP) using the table above.
- Multiply that GP by the Course Credit Hours. This creates your Quality Points.
- Add all your Quality Points together.
- Add all your Credit Hours together.
- Divide the Total Quality Points by the Total Credit Hours.
Example Calculation (1st Year Student):
- Major Subject 1 (4 Credits): 65 Marks → B+ (3.25 GP) → 4 × 3.25 = 13.00 Quality Points.
- Major Subject 2 (4 Credits): 71 Marks → A- (3.50 GP) → 4 × 3.50 = 14.00 Quality Points.
- Non-Major Subject (2 Credits): 58 Marks → B- (2.75 GP) → 2 × 2.75 = 5.50 Quality Points.
Total Credits: 10.
Total Quality Points: 32.50.
CGPA: 32.50 ÷ 10 = 3.25.

Handling In-Course, Practical, and Viva Voce Marks
The NU evaluation system splits 100-mark theory courses into two segments: In-course evaluation (20 Marks) and the Final Written Exam (80 Marks).
- Combining Marks: The grading scale applies to your total combined score. If you receive 15/20 in your in-course and 50/80 in your final written exam, your total mark is 65 out of 100. Enter "65" into the calculator.
- Separate Passing Condition: You must pass both segments independently. If you get 18 in your in-course, but only 20 out of 80 in the final written exam, you will fail the course (despite the total being 38) because you did not meet the minimum 32-mark (40%) pass threshold for the written section.
- Practical & Viva Voce: For science students (Zoology, Chemistry, Physics), practical exams have distinct course codes and distinct credit hours (usually 2 or 4 credits depending on the year). Treat practicals and viva voce as separate, individual subjects in the calculator.
Improvement and Retake Policies
National University offers an "Improvement Exam" system. If you pass a course but are unsatisfied with your grade, you can sit for an improvement exam in the following academic year—provided your original grade was a C, C+, B-, B, B+ or A-. (You generally cannot improve an A or A+).
If you fail a course (F Grade), you must register for a "Retake." When you successfully pass a retake or improvement exam, the new Grade Point completely replaces the old one in your CGPA calculation. Use our calculator to simulate your "Target CGPA" by inputting the marks you hope to achieve in your upcoming improvement exams.
Frequently Asked Questions (FAQs)
To pass any course at National University, you must obtain a minimum of 40% of the total marks (which translates to a Grade Point of 2.00 or a Letter Grade 'D'). You must also meet the passing criteria for both the in-course assessment and the final written exam separately.
Practical exams are assigned their own specific credit hours in the NU syllabus (e.g., a 50-mark practical is usually 2 credits, while a 100-mark practical is 4 credits). Treat the practical exam as a completely separate subject. Enter the marks obtained and select the corresponding credit value.
If you score below 40% (an F grade), you earn 0.00 Grade Points for that subject. However, the credit hours for the failed subject are still added to the total credits (the denominator). This mathematically drags your entire CGPA down drastically until you sit for a retake exam and replace the 0.00 with a passing grade.
Yes. A CGPA of 3.00 is officially equivalent to a "1st Class" degree. This secures your eligibility for all major government competitive exams, including BCS and state-owned commercial bank officer roles.
