Hi,

The simplest way through which you can get the mostly frequently asked questions or important question is to go through the previous year's question papers of that subject.

Most of the times in state board papers and even in CBSE there are some topics which are repeated mostly. Sometime the question is directly repeated or sometime they ask the same topic but with changing the question pattern.

So I will suggest you to go through the previous years question papers and observe them carefully. This will not only help you to find out the important topics but the nature of paper also. Rest of your success depend on your hardwork.

Hope it helps. All the best.
