Hi Sameer,

If you are in class 11 and you want to start the preparations now itself, then it is a very good step. You can definitely crack JEE mains if you study regularly. After you have completed each chapter, try solving MCQ types of questions of it. First study chapter wise and once you are done with all chapters, combine 6-6 chapters and answer tests. Don't start preparation of class 12th portion for JEE Mains till you don't finish your 11th final exams. Study with the flow. Answer some online mock tests. Refer to previous years question papers and start solving them. With that, you will vet brief idea on how to go about.

Remember, the questions asked for JEE Mains and advanced are not direct. They are applicative type of questions.
