First two weeks: Revise all notes again. Solve all the problems that were in the notebook to revise all tricks too. Solve all the questions that you have marked for revision in modules of each chapter.
Next two-three weeks : This phase lasted till the end of May. Most of your review packages should be completed so in those 2 weeks you just revise all good questions from review packages and some past tests. You can also start solving good problems from past 39 year questions, basically those ones which you asked as a doubt earlier from your teachers.
Final week : What is most important in this week is to be calm and composed. You don’t need to solve any new questions in this week, just carry on with revision of notes, inorganic chemistry and other part that had to be learned thoroughly. The reason for not studying a new trick or solving a new problem in this phase that if you are unable to solve it, it will become a doubt and since there was is time left for getting it cleared, it will only give you unnecessary stress.
You can easily see that most part was spent in revising things rather than solving some new book. I believe this is sufficient for getting a good result in JEE because there is already a lot to remember and focus upon.
