Formula Used
Base percentage formula:
Percentage Score = (Obtained Marks / Total Marks) × 100
Adjusted formula with bonus and penalty:
Adjusted Obtained Marks = Obtained Marks + Bonus Marks - Penalty Marks
Adjusted Percentage = (Adjusted Obtained Marks / Total Marks) × 100
Target marks formula:
Target Marks = (Target Percentage / 100) × Total Marks
Marks Needed for Target = Target Marks - Adjusted Obtained Marks
These formulas help estimate present performance, target gaps, and grading status from marks entered into the calculator.
