If you want admission in NITs, then your rank should be less than 20,000 i.e 175 marks in JEE Main and 93% in CBSE boards.

No, NIT offers aerospace engineering. Only a few IIT's (probably IITM, IITB, IIT Kanpur, IIT Khara) offer aerospace engineering. Highly competitive. You need to have a very good JEE rank to get in to these programs. Aerospace Engineering is not provided by any NIT, BITS or IIITs.

For that you should contact the admission department of that college and get relevant information about the eligibility criteria and entrance exam details for that college, then you will have a clear path towards study in that college.

Hello,
There may be chances of getting a good NIT college for chemical engineering.

To be on safer side, it would be better to get 90%+ in class 12th Board exams. The eligibility is just 60%, in order to get into IIT or NIT with that score you should score high in Mains.

Hi Adi,It is advisable to get in touch with the college officials for detailed information, as there is no such information available on the official website. Thanks.
