-
One concept per page: Avoid cramming multiple topics on one page for clarity.
-
Use diagrams and flowcharts: For GK topics like the Indian Constitution, historical timelines, and geographical features.
-
Formula sheets: Maintain a separate A4 sheet for all Maths formulas — revise this daily in the last month.
-
GK capsules: Create one-page summaries of each major topic (e.g., Battles of India, Constitutional Amendments, Important Dams & Rivers).
