Hello,

To make preparation easy, there are some ways you can use it like:-

1. prepare the chapters which feels easy to you and make sure you understand and prepare  them 100% such that you won't get confused in any way in the exam hall
2. Skip the part which feels new to you and don't start them if you are not much confident in it
3. Don't try to cover all the subject chapters. It won't be efficient as you will forget everything easily and get confused easily as practice is very less. Without practice no one can remember concepts.
4. Just do that much which you can with the time you have in your hand.
5. More important calm down and have patience and study and practice previous year papers. Appear mock tests of previous year papers and solve as many questions you can.

Hope it helps!
