JEE Main Scores

It changes every year and varies category-wise. So, the cutoff marks in JEE Mains are not constant.

I can't tell the score that you have to get in Mains as it varies every year. But you have to get a rank at least about 10k in JEE Mains to get into aerospace engineering. Then, you will be in the super-safe zone. Up to 15k, you can have a moderate chance.

Admission in NIT depends on rank not on marks. Tell me your category rank, home state rank. Board marks are just for eligibility, not for admission.

You can go for NIT-Warangal, Raipur and Calicut.
All these are very good options.

Of course, you can get admission for B.Tech. The fact is you will not get reputed college. After looking at your score you will end up with some local private institute. Although your 12th percentage are good but it won't help. As, per criteria colleges first consider your JEE score. There is one more choice to get top colleges that is through management quota. While applying through management quota you have to pay huge amount of fee as donation in terms of getting admission. So, if you are ready for management quota then go for it unless you have to go with your score and look out for some private institute.
Best of luck.

Sorry, for this rank, I couldn't find any college.
