What is SPI (Semester Performance Index)?

SPI, or Semester Performance Index, is a measure of a student's academic performance in a single semester. It is calculated based on the grades obtained in all subjects during that semester. SPI is crucial for understanding your performance in a specific semester and helps in identifying areas for improvement.

What is CPI (Cumulative Performance Index)?

CPI, or Cumulative Performance Index, is the cumulative average of SPI across all semesters. It reflects your overall academic performance throughout your course. CPI is often used by employers and higher education institutions to assess a student's consistency and academic excellence.

How to Calculate SPI and CPI?

GTU uses a standardized grading system to calculate SPI and CPI. Here's how it works:

• SPI Calculation: SPI is calculated by multiplying the grade points of each subject by the credit hours of that subject, summing up the results, and then dividing by the total credit hours of the semester.
• CPI Calculation: CPI is the average of SPI across all semesters. It is calculated by summing up the SPI of all semesters and dividing by the total number of semesters.
