Hello Rahul, here are some tips which you would find very useful while preparing:
1. When you start preparing for a question type take up as many questions as you can from good books and papers and try solving them.
2. Do not consider any type less important or insignificant because you never know which question type may be highlighted in this section.
3. Also, if you are unable to solve a few questions do make it a point to get it solved from a senior, teacher or a fellow student. Don’t leave any question unsolved.
4. Once you get in a habit of attempting these questions start focusing on your accuracy. Though it is important to attempt all questions it is equally important to do them accurately.
Hope it helps. 🙂
