Hello Vishal,
The syllabus as you know is as that for 12th of CBSE. So, first go through the book prescribed by CBSE. After you have done this, you can refer any book.

You can appear for JEE Mains and after cracking this exam you can appear for JEE Advance. If you crack JEE Advance with good marks you may be selected for any IIT.

Hello Yash,
The corrections are allowed only after the period of acceptance of an application form is over. 31 May 2017 is the last date to submit the application form. Hence, the window for corrections will open after this date.

Below mentioned are the best IITs:
1. IIT – Delhi.
2. IIT – Bombay.
3. IIT – Kharagpur.
4. IIT – Roorkee.
5. IIT – Madras.
6. IIT - Kanpur.

Devoting one full year for JEE preparation after completing class 12th has its own merits and demerits. Dropping a year means that you will get sufficient amount of time to prepare for competitive exams. It will allow you take mock up test and help to score good ranking in competitive exams.
However, one year is a long time, so the possibility of you may change your goals and objectives. You may become lethargic because of availability of time and lesser pressure.
