It would be better if you could share what is your current preparation status and the stream which you belong to.

Also, in case you just have started your preparation from scratch only then it would be good if you check the weightage of topics and accordingly devote your time because if your syllabus is not yet completed then 2 months would be little less. So check the weightage and make a proper study plan and distribute your time in a way that all your subjects get equal time.

Apart from this, read all your class notes and once you are done with your syllabus and important topics then start revising the same through sample and previous year papers.

Lastly, it is advisable to give your last 15 days in mock tests as these are easily available in market because these tests will be helping you to know all your weak and strong areas and accordingly you can revise them all and these will also teach you time management skills during exam and you will also get to know the exam pattern.

Good Luck!!!
