Start with errors, not the score
Separate your mistakes into concept gaps, calculation errors, reading errors and time-pressure decisions. The category matters because each type needs a different fix.
Use a three-pass review
Pass one: incorrect questions. Pass two: correct questions that took too long. Pass three: unattempted questions that were realistically solvable.
Create one improvement action
Do not turn every review into a giant new timetable. Pick the one pattern causing the most lost marks and address that first.
