Quick answer: IUB’s published grading regulation (for MPhil/PhD semester programs) uses a 4.00 scale: A+ = 4.00 (90–100%), A = 3.70 (80–89%), B+ = 3.30 (75–79%), B = 3.00 (70–74%), B- = 2.70 (65–69%), C+ = 2.30 (60–64%), C = 2.00 (55–59%), C- = 1.70 (50–54%), D = 1.00 (40–49%). GPA = Σ(credit hours × grade points) ÷ total credit hours. MPhil students need a CGPA of at least 2.70 and PhD students 3.00 to stay in good standing. For BS programs, check the grade scale printed on your result card or ask your department, because IUB has not published a separate BS grading table that we could verify.
The IUB grading system 2026 governs how marks are converted to grades, how GPA and CGPA are calculated, and what academic standing rules apply for all BS, MS, MPhil, and PhD students at Islamia University Bahawalpur. Whether you are a new student confused by letter grades on your first semester result, or a continuing student trying to calculate your CGPA for a scholarship application, this complete guide covers the full IUB grading system 2026 including grade letters, GPA points, CGPA calculation formula, promotion rules, probation conditions, and how to read your official transcript.

IUB uses a 4.00 grade-point scale for GPA calculation. Pass marks and the grade scale for BS programs can differ from the MPhil/PhD table above, so always confirm with your department or the grade scale on your result card.

IUB grading system 2026 — GPA calculation formula
GPA is calculated at the end of each semester. Here is the exact formula:
Step 1: For each course, multiply the credit hours by the grade points earned.
Step 2: Add all (credit hours × grade points) values together.
Step 3: Divide the total by the total credit hours attempted in the semester.
Formula: GPA = Σ(Credit Hours × Grade Points) ÷ Total Credit Hours
Example (using the official IUB grade points above): three 3-credit-hour courses with grades A (3.70), B+ (3.30) and B (3.00) give quality points 11.1 + 9.9 + 9.0 = 30.0; GPA = 30.0 ÷ 9 = 3.33.
IUB grading system 2026 — CGPA calculation
CGPA is the cumulative GPA across all semesters completed. Formula:
CGPA = Total Quality Points (all semesters) ÷ Total Credit Hours Attempted (all semesters)
Under IUB’s MPhil/PhD regulations a student gets one chance to improve a course grade; departments may also offer make-up or summer semesters (summer: up to two courses or 8 credit hours, with VC approval). Ask your department how repeated courses are counted in your program. A good CGPA also helps with merit-based awards such as the IUB Khushi scholarship 2026 and the HEC need based scholarship 2026.
