Is SGPA only for a single semester while CGPA is cumulative?

 Yes, exactly! Here's the distinction:

• SGPA (Semester Grade Point Average):

  • Calculated for a single semester.

  • Reflects your performance only in that semester.

  • Formula (generalized):

    $$SGPA = \frac{\sum (Credit_i \times GradePoint_i)}{\sum Credit_i}$$

    where $i$ runs over all subjects in that semester.

• CGPA (Cumulative Grade Point Average):

  • Calculated over all semesters completed.

  • Reflects your overall academic performance in the program.

  • Formula (generalized):

    $$CGPA = \frac{\sum (Credit_i \times GradePoint_i) \text{ over all semesters}}{\sum \text{Credits over all semesters}}$$

So SGPA is semester-specific, and CGPA is the running average across semesters.
