How can I manage both school syllabus and preparation for the IIT-JEE simultaneously?

 The syllabi of the IIT-JEE are nearly the same as that of CBSE Board exams. The only difference lies in the approach.

In IIT-JEE, students are asked problematic questions which require deep understanding of concepts whereas in CBSE Board Exam stress is given on reproducing the facts.

The best method of managing both is to be regular in classes, joining a good coaching institute and proper time management.
