How to Study Science

📐

Master the Formulas

Don't just memorize — understand derivations. Know when and why each formula applies. Practice applying them in different contexts.

🗺️

Draw Diagrams

Visual representation helps retain complex concepts. Draw circuit diagrams, cell structures, and reaction mechanisms by hand.

🔁

Spaced Repetition

Review topics at increasing intervals — after 1 day, 3 days, 1 week, 2 weeks. This dramatically improves long-term retention.

📝

Solve Previous Papers

Board exam patterns repeat. Solving 5 years of previous papers gives you a clear picture of important topics and question styles.

🔗

Connect Concepts

Science subjects are interconnected. Thermodynamics links Physics and Chemistry. Biochemistry links Chemistry and Biology.

⏱️

Timed Practice

Practice solving problems under time pressure. Board exams require speed and accuracy — both improve with timed practice sessions.
