Hi Satadal, if this is your all India ranking, then you will get Computer Science Engineering in NIT Agartala for sure. You will use your schedule caste category reservations, and get a seat in this college easily. So, you should keep all the documents ready for verification. If this is your sc category ranking then you can not get admission in this college. Best of luck.

It mostly depends on the branch you are interested in. If you are not worried about the branch then I would prefer NIT Jaipur as it an old NIT as compared to the other two.

No chance of getting chemistry honors at this percentile in NIT, Agartala.

No chance of getting any seat in NIT, Agartala.

Dear, there is a 50-50 chance to get admission there but don't wait. Just take admission wherever you are getting the seats. Just apply for it. You can also wait for some time to check the merit list. You can make a contact with admission officials .
All the best.
