sir,Till now i am good in mathematics ,physics and chemistry only upto board level..as chemistry do not need any extra afforts other than ncert so i am only worried about the maths and physicsAnd now no time is left to practice the jee level question from them ..So solving only last 10 or 15 year question paper can help me to prepare for jee level questions in the exam..?? plz reply!!!

surely , solving past years question help u alot but chemistry also needs revision, ncerts are sufficient but u need quality problems so that u can apply what u know. also organic chemistry needs more than NCERTs so i advise u to quickly go through theory from a good level jee book on organic chem.

best of luck.
