Understanding the CGPA calculation system at the American International University-Bangladesh (AIUB) is essential for academic planning, especially since your Cumulative Grade Point Average (CGPA) directly impacts your eligibility for scholarships, graduation, and academic honors. AIUB Grading Scale and Grade Points
AIUB uses a 4.00-scale grading system. The grade points (GP) assigned to each letter grade based on numerical percentages are as follows: Numerical % Letter Grade Grade Point (GP) 90 – 100 85 – < 90 80 – < 85 75 – < 80 70 – < 75 65 – < 70 60 – < 65 50 – < 60 Example Calculation: Let’s say you took three courses
Note: Special grades like I (Incomplete), W (Withdrawal), and UW (Unofficial Withdrawal) do not carry grade points but can affect your future academic standing. How to Calculate Your CGPA Manually
Your CGPA is the weighted average of all courses taken across all semesters.
Calculate Semester GPA: Multiply the Grade Point of each course by its Credit Hours to get the "Quality Points." Divide the total Quality Points by the total Credit Hours for that semester.
Calculate Cumulative GPA (CGPA): Sum up the Quality Points from all completed semesters and divide by the total number of credits earned to date. Calculation Example:If you take two courses: Course A (3 Credits): Grade A+ (4.00 GP) → Course B (3 Credits): Grade B (3.25 GP) → Semester GPA: AI responses may include mistakes.

To calculate your Cumulative Grade Point Average (CGPA) at American International University-Bangladesh (AIUB), you must follow the university's specific grading scale and weightage system. AIUB uses a 4.00 scale, where the calculation is based on the total points earned divided by the total credits attempted. 📊 AIUB Grading Scale
The following table shows how numerical marks translate into grade points at AIUB: Numerical Range Letter Grade Grade Point 90% – 100% A+ 85% – < 90% A 80% – < 85% B+ 75% – < 80% B 70% – < 75% C+ 65% – < 70% C 60% – < 65% D+ 50% – < 60% D F Calculation Formula
AIUB calculates CGPA by taking the sum of the products of grade points and credit hours for all courses, then dividing by the total number of credit hours. Formula:
CGPA=∑(Grade Point×Credit Hours)∑Credit HoursCGPA equals the fraction with numerator sum of open paren Grade Point cross Credit Hours close paren and denominator sum of Credit Hours end-fraction Calculation Example: If you take 3 courses in a semester: Course 1: 3 Credits, Grade A+ (4.00) →3×4.00=12.00right arrow 3 cross 4.00 equals 12.00 Course 2: 3 Credits, Grade B+ (3.50) →3×3.50=10.50right arrow 3 cross 3.50 equals 10.50 Course 3: 3 Credits, Grade A (3.75) →3×3.75=11.25right arrow 3 cross 3.75 equals 11.25 Total Points: Total Credits: GPA: 📝 Key Academic Policies
Graduation Requirement: Students must maintain a minimum CGPA of 2.50 to earn their degree.
Academic Probation: If your CGPA falls below 2.50, you are placed on probation for one semester. Failure to improve within the deadline can lead to termination. Retake Rules:
You can retake a course if the grade is below 2.50 (e.g., D+, D, or F). Course A (3 Credits): You got an A (4
For the first 4 F grades (Undergraduate) or 2 F grades (Graduate), the new grade will be used for CGPA, though the 'F' still appears on the transcript. Beyond this limit, both the 'F' and the new grade are factored into the CGPA. Academic Honors: Summa Cum Laude (Gold): CGPA 3.95 – 4.00. Magna Cum Laude (Silver): CGPA 3.80 – 3.94. Cum Laude (Bronze): CGPA 3.65 – 3.79.

4. Step-by-Step Calculation Example
Suppose a student has completed 3 courses in a semester:
| Course | Credits | Grade | Grade Point | Weighted Score (Credits × GP) | |--------|---------|-------|-------------|-------------------------------| | MATH101 | 3 | A | 4.00 | 12.00 | | PHYS102 | 3 | B+ | 3.30 | 9.90 | | ENG103 | 3 | A- | 3.70 | 11.10 |
Semester GPA: [ \textTotal Credits = 3+3+3 = 9 ] [ \textTotal Weighted Score = 12.00 + 9.90 + 11.10 = 33.00 ] [ \textGPA = 33.00 / 9 = 3.666 \approx 3.67 ]
For CGPA, the same formula applies across all completed semesters.
Example Calculation:
Let’s say you took three courses in a semester:
- Course A (3 Credits): You got an A (4.0). Quality Points = $3 \times 4.0 = 12$.
- Course B (3 Credits): You got a B+ (3.3). Quality Points = $3 \times 3.3 = 9.9$.
- Course C (1.5 Credits): You got a C (2.0). Quality Points = $1.5 \times 2.0 = 3.0$.
Total Credits Attempted: $3 + 3 + 1.5 = 7.5$ Total Quality Points: $12 + 9.9 + 3.0 = 24.9$
SGPA = $24.9 / 7.5 = \mathbf3.32$
To get your CGPA, you repeat this process for all semesters you have completed so far, summing up the total credits and total quality points, then dividing them.
Common Mistakes to Avoid
- Including Incomplete (I) grades: Do not add “I” grades into a CGPA calculator. They carry 0 points but also 0 credits until resolved. Instead, exclude them until a letter grade is assigned.
- Ignoring Credit Hours: A 1-credit lab course has much less weight than a 3-credit theory course. Always double-check credit hours from your syllabus.
- Rounding Errors: CGPA is usually truncated to two decimal places (e.g., 3.69, not 3.695). Avoid rounding individual grade points prematurely.
5. Algorithm / Pseudocode
Input: list of courses where each course has credits, gradeLetter
Map gradeLetter -> gradePoint (use AIUB table)
qualityPoints = 0
totalCredits = 0
for each course in list:
if course.gradeLetter in countedGrades:
gp = gradePoint(course.gradeLetter)
qualityPoints += gp * course.credits
totalCredits += course.credits
if totalCredits == 0:
CGPA = 0
else:
CGPA = qualityPoints / totalCredits
Output CGPA rounded per official rule
For cumulative updates, store cumulativeQualityPoints and cumulativeCredits and add term values before dividing.
