I was in 12th last year and i have got some useful experience of class 12 , which could help you. Me and all my class fellows were told from starting that 12th is most important part of your life. Your future college will be decided according to your 12th result. The more marks you get , the more chances of your higher salary in future job you earn. Well most people somehow manage to get good marks in Maths and Chemsitry. But where they fail to mark good is PHYSICS. I will be truthful , i didn't read anything in whole session and during exam i just revised last year question papers. Don't know how but i managed to get 46 marks out of 70. So think, what could happen if you work hard and do some proper revision. Here are Three main steps you should follow to score high in Physics 1. Learn and Revise NCERT by heart . 2. Don't focus on Numericals much. 3. Revise last 10 years of Physics Board Exam Question Papers.
