Dear Raunak,

Prepare for JEE, you will surely score good in cbse.. And regarding solving problems keep trying .. Never prefer solutions of questions before doing SELF-ATTEMPT at least five times till you get the right answer because "without fall you can not stand at once". 

Alear and enhance your concepts .. jus keep this thing in mind that building concepts and practicing a lot is damn important for IIT preparation..

Dont let ur confidence down.. try your best and believe in yourelf .. study without loosing the concentration coz studying 2 hours with very good concentration is equals to studying 5-12 hours without any concentration. .
