How to Study Formulas for Different Exams
- Memorise the formula, then study the NCERT derivation.
- Practice every NCERT in-text and exercise numerical.
- Pay attention to units — marks are deducted for missing units.
- Formulae from previous year papers repeat frequently.
- Use the solved examples in each article as a revision checklist.
- Understand derivations — JEE tests conceptual application, not rote recall.
- Learn all formula variants and edge cases (e.g., relativistic KE).
- Note dimensional analysis — it can eliminate wrong options in MCQs.
- Study the JEE/NEET section in every formula article for exam patterns.
- Revise the “Common Mistakes” section before mock tests.
- Focus on Physics and Chemistry formula chapters: thermodynamics, optics, organic reactions.
- NEET numericals are mostly single-step — speed and accuracy matter.
- Memorise SI units and constants (Planck’s constant, Avogadro’s number).
- Use the FAQ section in each article to revise definition-type questions.
- For Chemistry, focus on Mole Concept, Electrochemistry, and Chemical Kinetics.
