IIT

If you are a average student and know your capabilities then you have to work hard, study hard, concentrate and be focus on your studies only and not anything else .
Just go with the concepts of subject of 11th and 12th , practice NCERT as much as you can, Try to solve every question of the book. Go for previous year paper if you want to go for coaching then choose good coaching for the preparation but do not totally depend on it. Do more self study.
You will definitely qualify for 1 attempt in JEE Main.Also if you are of general category then actually you have to study hard.

90% of students have a very bright career in IIT in this epic period.

Firstly, understand none of the IIM's awards an MBA degree as far as placements are concerned IIM's would have a slight edge over the IIT's. But, that is because you can't equate 10 engineering branches to 4 MBA specialization. A top CS graduation from IIT has better opportunities than an average IIM guy.

NCERT books are best for JEE preparations.

If you belong to general category, then you are not qualified since the cutoff for general is high. 60 marks is not enough for OBC category to qualify for Advanced. However, it shows your effort that although you have not qualified, but you gave your best to it. Many college ask for this score. Go for private colleges for the admission to B.Tech programme. There are many good college with affordable fees structure. Best of luck.

Hello Awdhesh,
Yes, you can get a college via JEE counseling. But you may or may not get a top college or the course you wish to get. It is difficult to say your rank as it depends on the number of candidates and their scores.
All the best!
