When the paper comes back, look past the mark to the mistakes. Sort each one: a concept gap (you did not know it), a careless slip (you knew it but slipped), a time problem (you ran out of minutes) or a misread question (you answered something else). Redo the wrong questions, ask about doubts, note weak topics in a mistakes notebook and update your plan. Percentage = marks ÷ total × 100.
