The best way for you to prepare is by using previous year question papers.

I would suggest you should attempt the same paper multiple times, at least 3 times, and then look at the solutions to all the questions you have not got right.

Keep on repeating the papers, do not attempt same paper two times in a row though. For example there is paper 1 you have given on day 1, then paper 2 on day 2 and then paper 3 on day 3. After that repeat, paper 1 on Day 4, Paper 2 on Day 5, and so on.

You can also attempt two papers in one day as the time comes to end.

Hope this helps. Thank you.
