Hi,
With such a low percentage you won't get any IIT. It is better to try for NITs.

No, even BITS has very good placements.

According to my knowledge it depends on timings of the coaching institute. Self-study is most important, the timings of coaching institute should not be over heaping. If you are an average or above average student then study regularly and practice MCQs daily as per the education provided in the college.

Yes, MBA from IITs like IIT-B / D / KGP is very profitable. MBA from IITs are known for ROIs. IIT-B / D are ranked higher than most of the premiere B-schools of India.

No, IITs do not accept any other entrance exam.
