Is your GPA based on grades at the end of trimester or all grades?

Typically, a GPA (Grade Point Average) is calculated based on the grades obtained at the end of each trimester. This means that the grades achieved in assignments, exams, and other assessments throughout the trimester contribute towards the final GPA. However, some institutions may have variations in their grading systems and methods for calculating GPAs, so it's always best to refer to your institution's academic policies for specific information on how GPA is calculated.
