🗓️ 7-Day Smart Revision Plan

Day 1: Revise momentum basics, sign convention, COM concept
Day 2: Elastic & inelastic collision formulas + examples
Day 3: Explosion problems & COM frame thinking
Day 4: Bounce problems, coefficient of restitution
Day 5: Objective questions (easy → moderate)
Day 6: Tough IIT/JEE objective & traps
Day 7: Full revision + mistake notebook

Golden Rule: Every day revise formulas for 10 minutes.
