IIT

IIT tag is surely worth a year but only if you are willing to sacrifice most of the things. Hard work always pays. But on the other hand, if you feel that NIT is worth it, then you should give it a try.

Yes, you can get any of private college you want to go with. Because in private college, you can take admission without any entrance exam. But JEE marks valid only for one year. So, you only can join private college.
Good luck.

Hello, Shaily. First of all, good luck. I hope you will do well in near future. For physics you can consider these books:
1-Engage (most important)- Independent edition
2-TMH-As a whole worthy
3-ML Khanna-Coordinate Geometry
4-Admit M Agrawal -Differential & Integral Calculus only
I am not mentioning books like Irodov and Krotov because these books are full of heavy subjective questions which can be learnt easily by solving previous years IIT questions.

In Physics:
University Physics Resnick Halliday
University Physics Sears & Zemansky
Problems in General Physics Irodov
GP Thomas Calculus for Beginners
Organic Chemistry Morrison Boyd.

You need to opt for state counselling in which state you want to get any government college. Go through the counselling procedure. Then you will be shortlisted for the college that you can get according to your score of JEE and 12th marks. All the best.
THANK you.

The best IIT for CSE is IIT Bombay. It was ranked 1st last year. Other than IIT Bombay, you can go for IIT Kanpur, Madras and Delhi.

Better try for next year. You will not get a good college at this rank. If you have filled other forms and if you get selected in other exams, then better go and join. Don't go for bad colleges. Go for a good college. All the best.

For second attempt, ask yourself why you did not succeed in the first attempt, if you genuinely believe you can improve on that reason. For example, if you were not well on exam day, try again. Please remember competition increases every year. If this year was tough, next year will be tougher.

There are other colleges, considering the cases like IIT ranks around 10000 and above you can attempt for two major Chemical and petroleum degrees from IIPE, (mentor by IIT KGP) Which is the 3rd year of the college. RGIPT, Raebareli, which provides degree in Petroleum but, there are likely to close around INR 15 k to INR 18k as well. There might be new addition, in some university seat or Scholarship based on JEE Advanced Rank. Read Advanced Brochure.
There are a few International colleges in Singapore that consider Advance Rank along with IISc Bangalore for it's Bachelor's Programs.
