  • 2-3 hrs: Analyze mistakes + revisit weak concepts
  • 1-2 hrs: Formula/theorem quick review
 Solve PYQs topic-wise then mixed; understand patterns & shortcuts (MathsCare GP Sir, Reddit consistent advice). Revise each topic 2-3x total this month.
Week 3 Full mocks + deep analysis
  • Alternate days: 3-hr full mock (exam timing)
  • 2-3 hrs: Detailed error analysis (concept/calc/time issues)
  • 1-2 hrs: Targeted weak-area fix
 Take 4-6 mocks; prioritize accuracy over speed first (PW last 30 days, Unacademy strategy). Track recurring errors.
Week 4 Light polish + relaxation
