100 Marks Lane Ki Strategy
Math me 100 marks lana mushkil nahi hai. Sirf sahi strategy chahiye. Yahan step-by-step plan hai:
Pehle 2 mahine me NCERT ki har exercise solve karo. Examples bhi karo. Har question samajh ke karo, ratna mat. BSEB ka paper NCERT se hi aata hai — ye sabse important hai.
Har chapter ke formulas ek jagah likho. Roz subah 10 minute revise karo. Test se pehle ye notebook padho. Formulas yaad honge toh MCQ bhi jaldi solve honge.
NCERT complete hone ke baad Rank Dangal app pe chapter-wise tests lo. Kam marks aane pe chapter dobara padho. Polynomials test, Quadratic test — sab available hain.
Full syllabus mock tests do. 3 ghante 15 minute me complete karo. Time management seekho. Accuracy improve karo. OMR sheet pe practice karo.
Last 5 saal ke papers solve karo. Important topics identify karo unhe extra time do. Exam se pehle 2-3 papers zaroor karo. Model papers secondary.biharboardonline.com pe available hain.
