Toppers' Tips for Effective Reading
Start with NCERT before any reference book — it builds the foundation that all other books rely on.
Make handwritten notes while reading — writing reinforces memory far better than passive reading.
Revise each chapter at least 3 times — spaced repetition is the key to long-term retention.
Solve worked examples before attempting exercises — understand the approach before applying it.
Combine reading with mock tests on HenceProve — practice under exam conditions to build speed and accuracy.
