Rank Dangal Tip
Roz 30 minute MCQ practice karo. Rank Dangal app pe har chapter ke 20-25 VVI objectives available hain. Mock test pe real exam jaisa pressure feel karo. Isse tumhari speed aur accuracy dono improve hogi!
Subjective Questions Strategy
Subjective me 2 marks aur 5 marks ke questions aate hain. Inke liye alag strategy chahiye:
Examiner ko paragraph nahi chahiye. 3-4 points me answer likho. Har point ko underline karo. Isse marks milte hain. BSEB me checking achhi hoti hai agar answer organized ho.
Science me diagrams se 1-2 extra marks mil sakte hain. Mirror, lens, heart, brain, neuron — ye sab diagrams practice karo. Pencil se properly banao aur labels lagao.
Numerical questions me formula likhna mat bhulo. Formula likha to 1 mark mil jayega, even agar answer galat bhi ho. Physics me ye bahut kaam aata hai.
Answer me real-life examples do. Jaise — "Corrosion ka example: Iron ka rust hona" — isse answer strong lagta hai aur examiner impress hota hai.
Science me definitions bahut important hain. NCERT ki language use karo. Keywords underline karo. Jaise — "Ohm's Law ke according current, voltage ke directly proportional hoti hai jab resistance constant ho."
