CBSE 12th

For getting a good college, you need around 85-90 percentile in the CAT exam. With your percentile you can expect a tier 2 or tier 3 college.

Hi,
You require 85-90 Percentile to get a call from BIM. But there are many other factors which give you a weightage along with your CAT overall score like your academic records, work experience, your extra curricular activities & your overall profile.

Hi,
The cut-offs for NITT for MBA generally range from 85 to 89%. So, you have chances of getting NITT for an MBA.

It would be very difficult for you to get IIT, as these many marks are not sufficient for IITs.

You have a very low % and admission will be very tough for you. Since this is a private university you can try your luck, otherwise you may have to arrange for management quota etc.

You can apply for CUET if you do not have the 12th marksheet. You can attach your provisional result/marksheet or give an undertaking, as appearing candidates are given relaxation in this regard.

Hi
For general category students, the cut off for B.Com can go as high as 98-99%, and if you are christian then there might be some relaxation. But you will have to check the website for exact previous years. Cutoffs. Also, general category students do not have any free seats.
