MBA Entrance Exam

Refer college rankings of reputed magazines. I got into Doon Business School, Dehradun last year with 93.5 % in CAT.

Please give the ATMA exam, aim higher, give more mocks. You will be eligible for the DTE rounds with ATMA scores and will fetch you a good college as well.

Usually, 90 above to the top 6 and the new campuses are lower.

You can get admission through cap round such as
Lala Lajpat Rai Institute of Management, Guru Nanak Khalsa College, Thakur College, Sinhagad Institute of Management, Rizvi College.
These are the college which are a good option. But after cap round you can also try MET, IES.

Yes, obviously he or she can apply. But, he will be able to do that for next exam. Not for the same exam.

Yes, it affects, but the amplitude depends on college to college. Each college provide their respective weight-age on their website example IIM Indore gives very high weight-age to your past academics (even more than CAT whereas IIM Kozhikode gives a low weight-age to past academic record. So, you can check on each college website what are their weightage for past academics and prepare accordingly. This would help you to keep realistic goals.
