The Error Log
After every mock, create a table with four columns: Question Number, Type of Error, Correct Approach, and Key Learning.
Calculating 'Accuracy' vs 'Attempt Rate'
Are you getting 90% right but only attempting 50 questions? Or attempting 90 but getting half wrong? Your strategy depends on your current quadrant.
Pro Tip: Re-solve the mock after 2 days without looking at your previous attempts. If you still get the same questions wrong, it's a conceptual gap.
