Answer: To calculate CGPA (Cumulative Grade Point Average) from marks, you’ll need to know the grading system used by your educational institution. Typically, CGPA is calculated based on the grades you receive in your courses, where each grade has a corresponding grade point. Here’s a general process to calculate CGPA:

  1. Determine the Grading System: Find out the grading scale used by your institution. This usually involves letter grades (like A, B, C, etc.) and their corresponding grade points (like 4.0, 3.0, 2.0, etc.).

  2. Convert Marks to Grades: Based on the grading scale, convert your individual course marks to corresponding letter grades. For example, if the scale is A = 90-100, B = 80-89, C = 70-79, and so on, assign the appropriate letter grade to each course based on your marks.

  3. Calculate Grade Points: Using the grading scale, assign the appropriate grade point to each letter grade. For instance, if A = 4.0, B = 3.0, C = 2.0, and so on, assign these grade points to the respective letter grades you received.

  4. Calculate Weighted Grade Points: Multiply each course’s grade point by the number of credit hours for that course. This gives you the weighted grade points for each course.

  5. Sum the Weighted Grade Points: Add up all the weighted grade points from all the courses you’ve taken.

  6. Calculate Total Credit Hours: Sum up the total credit hours of all the courses you’ve taken.

  7. Calculate CGPA: Divide the sum of the weighted grade points by the total credit hours. This gives you your CGPA.

The formula to calculate CGPA is:

CGPA = (Sum of Weighted Grade Points) / (Total Credit Hours)

It’s important to note that different institutions might have variations in their grading scales and methods for calculating CGPA. Always refer to your institution’s guidelines and grading system for accurate calculations.

Also, keep in mind that the actual calculation process might involve rounding, minimum passing grades, and other specific rules defined by your educational institution.

To calculate CGPA (Cumulative Grade Point Average) from marks, follow these steps:

  1. Convert each subject’s marks into a grade using the grading scale provided by your institution.
  2. Assign grade points to each grade according to the grading system.
  3. Multiply the grade points of each subject by the respective credit hours of that subject.
  4. Sum up the total grade points earned across all subjects.
  5. Divide the total grade points by the total credit hours to get the CGPA.

For example, if you have three subjects with grades A, B, and C, and their corresponding credit hours are 3, 4, and 2 respectively, and their grade points are 4.0, 3.0, and 2.0 respectively:

Total grade points = (4.0 * 3) + (3.0 * 4) + (2.0 * 2) = 12 + 12 + 4 = 28

Total credit hours = 3 + 4 + 2 = 9

CGPA = Total grade points / Total credit hours = 28 / 9 ≈ 3.11

Remember, the specific grading scale and credit hours might vary by institution, so make sure to use the correct values for your calculation.
