How CGPA Is Calculated
Quality points for each course are found by multiplying the grade point earned by the course credit hours; GPA (per semester) and CGPA (cumulative) are the sum of quality points divided by total credit hours attempted.
An F grade remains permanently on the transcript even after the course is retaken and passed. Failing the same course three times leads to cancellation of admission, though the student may be permitted to change major or school instead. An I (Incomplete) is awarded only after at least 75% class attendance plus a valid, strongly discouraged, unforeseen reason; it converts automatically to F if not resolved by the end of the following semester. A W (Withdrawal) may be used a maximum of two times per course.

Retaking a Course
A student may retake a course to improve CGPA within the next four semesters of the original registration; a course must be retaken in the immediate next semester if the grade earned was F or below the minimum acceptable prerequisite grade for the student's School/Department.
Only the latest grade earned counts toward CGPA when a course is retaken. Any given course may be retaken twice only.

Academic Probation
A CGPA below 2.00 places a student on academic probation.
- If CGPA stays below 1.50 for two successive probation semesters, admission to the University is cancelled.
- If CGPA is 1.50 or above but still below 2.00, the student continues one further semester on probation and must raise CGPA to 2.00 or above by the end of that third semester, or admission is cancelled.

Minimum CGPA for Graduation
A cumulative grade point average (CGPA) of at least 2.00 is required to graduate from all IUB undergraduate programs. Graduation additionally requires a minimum of two academic years in residence and completion of all university, school, major/honours, minor and elective requirements. Individual schools may set higher minimum grade-point requirements for a student's own major courses at the 300 level and above.

Dean's List and Graduation Honors
Full-time students with strong semester CGPA are recognized on five honour lists: Dean's List (CGPA ≥ 3.50, any semester), Dean's Merit List (≥ 3.50, second successive semester), Dean's Honour List (≥ 3.76, second successive semester, with a Tk. 5,000 award voucher), Vice Chancellor's List (≥ 3.50, third successive semester), and Vice Chancellor's Honour List (≥ 3.86, third successive semester, with a Tk. 10,000 award voucher).
Graduating students with high cumulative grades, following North American practice, are recognized as Cum Laude (CGPA 3.60–3.79), Magna Cum Laude (3.80–3.94) and Summa Cum Laude (≥ 3.95). The Chancellor's Award, a gold medal, goes to a student sustaining a CGPA of 4.00 across the final four successive undergraduate semesters.

Transfer of Credit
To transfer credit from another accredited institution into IUB, the minimum acceptable grade per course is B- across all Schools/Departments, and the student's overall CGPA at the sending institution must be 2.50 or above.
An admission-test waiver additionally requires at least 30 completed credit hours at the earlier institution, an overall CGPA above 3.00 there, and a grade of B- in the intended course(s).
