Exam grades are determined by converting your raw score (marks obtained) into a percentage, then mapping that percentage to a letter grade based on the grading scale used by your institution. Different schools and universities use different grading scales, with the most common being the standard A-F scale and the plus/minus scale that provides more granularity.

Some courses use weighted grading where different components (exams, assignments, projects) contribute different percentages to your final grade. The weightage feature in this calculator helps you understand how much your exam score contributes to your overall course grade.
