Hello,

In order to build the concepts strong for JEE preparation, study two subjects among PCM every day. Try to solve questions on a regular basis. You can increase the speed of solving questions gradually. Minimum 30 questions per subject per day will be a great help. Make a list of all the formulae. That will help both in competitions as well as board exams. The concepts which you learn everyday must be written in a notebook which can be revised later on. On weekends, take a test paper and solve that within a given time frame. If you can solve the questions within 1-2 minutes, you can solve more problems very easily. Solving questions having variety will assist in tackling numerous problems within a specified period of time. For concept building in physics, chemistry and mathematics, you can refer to some special books such as :

Physics - Concepts of Physics, HC Verma

Chemistry - NCERT textbook

Mathematics - RD Sharma, NCERT Examplar,etc.
