IIT

Hello Ankush,
Most of the people prefer to prepare itself only so don't get dishearten and work hard, and regarding books, you can choose Cengage and Arihant Publications books for both physics and maths and for chemistry books like NCERT, Top Tandon, Ranjit Shahi, etc.

Yes, surely, a successful drop can change year life but for this, you need to do lot of hard work.
For the complete 1 year, you have to sacrifice with each and every thing and should concentrate only on your studies. So, if you are ready to sacrifice and study well. You can take a drop.
Hope this helps.
All the very best.

Hello Tarun,
All IITs are good but for getting the top IITs like Bombay, Madras, Kanpur, Guwahati, etc. Your rank should be below 1000 or 1500 for getting computer science engineering. It is one of the top courses offered and the IIT Bombay is considered to be the best for CSE.

Hi Vaibhavi,
Yes, you can appear for the IIT JEE exams after completing your 12th privately however the board has to be recognized one. To get admission in IIT you must of course clear the JEE Mains and Advanced.

To get admission in any IITs, you first need to crack JEE Mains paper-1 and then JEE Advanced and you need atleast 75% in boards to be eligible to get admission in any IITs.

If you score 250 in JEE Mains, then you got a very good rank in JEE Mains and not in JEE Advanced.
You must have to score good in JEE Advanced to get a good rank in this.
Good luck.
