like i mentioned before.. my cgpa is around 9.2 to 9.4... my basics are not that strong...is it possible for me to improve my fundas by 2015 and crack iitjee. and comin to coaching classes.. which is preferable intergrated ones or the class rooom program ones??

Yes,it is never late to learn anything.As you have good cgpa you can easily improve by keeping little interest also.

As you are in 10th grade and want to clear IIT-JEE, the main thing that is really important is to have very clear basics.

Some steps you can do are:

. clear your basics of maths and physics from your earlier classes (9th and 10th).

. Make sure you read a good book that has sufficient THEORY and not just solved questions (such as NCERT). Read the experiments/theory from NCERT as they are actually very important although they might seem trivial.''

. If you plan on joining a coaching institute, feel free to experiment with different institutes for the first month and  take a note of the following:

    - quality of teaching (i.e. more note dictation or more teaching_

    - importance of doubt clearing

    - weekly tests/monthly tests

- class room programs
