How do I stop forgetting formulas the night before?

Bhai, raat ko padhte waqt formulas bhoolna sabse common problem hai, but iska ilaaj simple hai. Active recall use karo — bas padhna nahi, khud se yaad karo. Pehle formulas ko ek formula sheet par likho, phir usse cover karke har formula ko zor se bolo. Jo yaad nahi aata, usse red pen se mark karo aur dobara revise karo.

Spaced repetition follow karo — ek baar mat padho, 2-3 baar repeat karo with gaps. Example: raat 10 baje padho, phir 11:30 baje revise karo, phir subah 5 baje dobara. Isse brain mein long-term memory ban jati hai.

Mnemonics ka istemal karo. Jaise physics mein $∫ u\,dv = uv - ∫ v\,du$ ke liye ILATE rule yaad rakho. Chemistry mein periodic table ke liye "H He Li Be B C N O F Ne" ko aise yaad karo: "Hi Hello Little Boring Cute Nana On Friday Night".

Sleep ka raaz — 7-8 ghante ki neend zaroor lo, kyunki neend ke dauran brain consolidation karta hai. Subah exam se pehle sirf formula sheet ko 10 minute mein dekho, confidence ke saath paper do.

Ek micro-example: agar tum $rac{d}{dx}x^n = nx^{n-1}$ bhool rahe ho, to ek baar khud se bolo: "differentiate power, bring down n, reduce power by 1". Phir ek practice karo: $rac{d}{dx}x^3 = 3x^2$. Aise hi har formula ko chhota rule mein tod do.

Aur haan, positive thinking rakho — jo yaad hai, wahi enough hai. Overthinking mat karo. All the best!
