How do I stop forgetting formulas the night before?

Bhai, raat ko formula yaad karna is like trying to cram a whole biryani in one bite – possible but risky. Use active recall: write formulas without peeking, then check. Make silly mnemonics or stories. Use spaced repetition – revise formulas in the morning, afternoon, and night. Teach someone else – if you can explain it, you know it. Sleep is gold – your brain consolidates memory while you sleep. So, revise smart, not hard, and sleep 7-8 hours. All the best!
