Hey durga

15 days is very little time left, but if you put enough effort you can still score well in JEE.

So go through revise and re read everything you alreadyknow. Make formulae sheets or flash cards and revise them as much as you can. Practice a few previous years papers and see where you are lacking.

Focus on those areas. There are topics from every subject that carry a lot of questions and are not very hard to prepare. Go through those lessons and prepare for them if you haven't already.
