I hope this will help you.

Congratulations for soring good rank and as of your rank you can get in any college which you are interested and I suggest VVIT college and coming to branches choose either CSE or ECE thank you.

If you have got more than 75% in 12th board exam and you are being allocated any seat through JoSAA, you are eligible for getting admission.

Your 11th marks doesn't matter in JEE all that matters is how well you have performed in JEE and whether your 12th board marks are above 75% or not.

I would say initially get mug the NCERT Books completely.

Anyone can be entrepreneur. Related to your IIT and BBA it should depend upon your interest and career goals. Well do research about it and take decision wisely.

IIT attract 9000 jobs in the first phase of campus hiring, including 160 offers of Rs 1 crore plus annual salary.

For admissions into IITs, the candidates will be required to meet the following criteria: Candidates must have cleared 12th standard (or equivalent) examination. The candidates should be within the top 20 category percentile of the qualifying examination.

Your chances are low. Sorry, all the best for next year.

You can get CSE IN IIT DHARWAD, IIT PALAKKAD, IIT BHILAI, IIT JAMMU
ECE in ISM DHANBAD
MATHEMATICS AND COMPUTING in IIT GOA, IIT PATNA
If you can lower your branch choice than there are lot of options available for you in TOP IIT's like IIT KANPUR and IIT Kharagpur.
