How to use the checklist

  1. Mark topics you can explain, topics needing practice and topics you have not studied.
  2. Complete the prerequisites before attempting mixed problems.
  3. Keep all four subjects in your routine; the 2026 score combines all four sections.
  4. Use PYQs to learn the style of questions. Past frequency does not remove a topic from the syllabus.
