The first step to be prepared for these entrance exams begins in class 11 because of the fact that the  Exam Syllabus comprises of class 11 and class 12 syllabi for the subjects Physics, Chemistry, Mathematics, Biology.

A one year preparation period, along with class 12 studies can make it a little too stretched for everyone. There have been many cases where students were eventually forced to drop for a year after class 12 to prepare well.

Class 11 syllabus becomes the core of the entire syllabi across the four subject domains. So, while they prepare for their school exams, students can simultaneously start referring to IIT Books for class 11.

Such a steady and distributed stepwise approach not only assists with preparing the subjects well but is also helpful towards adopting a stress-free regime.
