Dear Jeet

If you are perfect in your 12th ,then your half prpration is completed.

so from now you need to work hard to get good rank in IIT JEE.

for 12th standard most effective and possible way is

besides school and coaching hour you should give 4-5 hour in your home for IIT JEE Prepration.

and for the rest of your board subject except(P C M) you can give 1 hour per day and 3-4 day in week.

You have 4 month left and this is sufficient for revision

I will suggest you to start from the begning. first revise your old notes in the same order as you was tought in coaching.

also refer good books of that topic. then solve standard question from books and IIT study material

and after finish the topic solve question of that topic from previous IIT JEE papers.
I will also suggest you to join test series.it will help you a lot for you prepration.

you can join online test series it will save your time.

Hi,

You are not late to start a preparation ….yes its true that cracking iit is not an easy job but its not impossible ... You will have to work hard for thorough study which you can do ..and alweys revise the material after coming back from school or coachings ... it wont take much time but it helps alot in remembering things for long time. Make a time table and cover the topics from 11th and 12th. If you are not confident about your 11th then work hard to cover 11th sllybus..Divide ur time accordingly  … Join some coaching institute, test series etc & forget all your other activities for few months !!!... Do not do a lot of books…..clear your concepts and give them more time to practice question. Do hard work and believe in yourself… I hope that helps.
