Last minute revision for chemistry exam

For last-minute revision for your Class 12 CBSE Chemistry exam, focus on key concepts, equations, and reactions. Here's a quick checklist: 1. Organic Chemistry:  Revise the naming conventions, functional groups, reactions like substitution, addition, elimination, and important named reactions. 2. Inorganic Chemistry:  Pay attention to the periodic table trends, chemical bonding, coordination compounds, and important reactions. 3. Physical Chemistry: Review concepts like thermodynamics, chemical equilibrium, electrochemistry, and solutions. 4. Practice Numerical Problems: Especially in physical chemistry, practice solving numerical problems related to various concepts. 5. Important Equations and Formulas:  Have a cheat sheet handy with important equations, formulas, and constants. Also, focus on any topics or chapters where you feel less confident and prioritize those during your revision. Keep calm, stay focused, and trust in your preparation. Good luck!
