Hi Prateek,

The Joint Entrance Examination is the most competitive examination not only in the country but in the world. Due to this, the effort required to clear it should be a lot. First of all, you need to be clear with your 11th and 12th basics. However, school syllabus is not nearly the same difficulty level. So, I advice you to go for other reference books. Practice and perseverance is the key to crack JEE or any other examination in the world.
