IIT JEE Online Material
Slowly my effort to record my relearning effort is bearing fruit, as I am continuing adding material. The material is more in chemistry site. But once I complete posting the basic material in all the chapters of chemistry, I can take up physics also. I am happy that I shall be in a position to provide some free IIT JEE material which at least will serve the purpose of additional reading for many persons.

Study Plan
Study plan basically consists of 10 days of study and problems solving. Additional 10 days is for revision and for solving some more problems from the book, if you could not complete them during the first 10 days. Each day spend at least one hour for this subject for the main chapter and may be 15 minutes to 30 minutes for revising the earlier chapter. Thus you have to allot at least three hours and forty five minutes every day for your self study. It will be good when you are able to combine your self study with the lecture that is going in the school and coaching class. That way you will be able to complete self study in lesser time and get the benefit of reinforcement.

Study Plan
Study plan basically consists of 10 days of study and problems solving. Additional 10 days is for revision and for solving some more problems from the book, if you could not complete them during the first 10 days. Each day spend at least one hour for this subject for the main chapter and may be 15 minutes to 30 minutes for revising the earlier chapter. Thus you have to allot at least three hours and forty five minutes every day for your self study. It will be good when you are able to combine your self study with the lecture that is going in the school and coaching class. That way you will be able to complete self study in lesser time and get the benefit of reinforcement.
