CBSE

Yes. As you have got 97.05%ile in JEE you are competent enough and eligible enough to apply for it and to secure admission so go for it and apply.

No, It's not possible for you to get admission in any of the NITs as the seats are limited to less than 600. So, those who get AIR of less than 1400 will get seats in NITs. I suggest you to go with private institutes.

You can try by BA in History. The cut-off is usually above 95% for non-christian general category.

For BMS, there is a written exam plus a PI, I don't think that you can get in with 75%.

Sorry, but you cannot get admission for B.Sc in Computer Science in Vellore. Your score in CBSE is too low for this seat. You should just choose another college.

Hi Himanshu,
As you have already completed your class 12th board exams with 78% marks, so you are eligible to take admission in BCom honours course of this college. You should apply for the same.
Best of luck.

Yes, you can take admission in Kolkata University but if anyone has higher marks then they will get first.

Hello Ankit,
Your score is not bad but it is difficult to get aeronautical engineering at Madras Institute of technology campus of Anna University since the competition is too high as well as there are many people with above 90 percent or so. Hence, you can try your luck at the time of admission or apply for other colleges.
