Dear jimmyu

Main thing is to clear the concept. you can clear the concept just by solving 20-30 question. some time for some student solving more than 200 question is not enough.So depending upon ur capability you should solve questions. I think u are revising your you should choose that topic in which you are weak.

Optics' too contributes approximately 10% to the IIT-JEE .  Within Optics, it has been observed that problems on Physical optics are more frequent than that on Geometrical optics. Students should  devote about 7% of time on Optics for robust preparation.
