Diploma

Hello,Provided you have scored at least 50% marks in your B.Tech, you are eligible to appear for the CAT and then join an IIM (if performed well in its interviews). Good luck.

Do you have any specific subject in your mind?, So, it will be very clear to me to help you with the best college according to your preference. Bangalore is a city with numerous colleges and universities. Please let me know which Diploma you are specifically looking for. Thank you.

Yes, you are eligible.

It's possible from 12th to B.Tech, but not after Diploma sadly. However, the best thing I would suggest is to contact the counsellor of the college or university for in-depth knowledge or guidance if you really want to do it.

With the above-mentioned score, yes a Diploma candidate with 84/200 marks in NATA exam can surely get admission in architecture course.
Best wishes.
