Hi

If vacancy and the merit suffices, you can get a seat. Though, you should put in the possible options so to increase your chances to get so. Also, you can look for North-East NITs or mediocre to low NITs also, though you won't be able to get the trending branches.

Yo can always check the same about NITs Cutoff for Top B.Tech Branches in a greater detail through this link: https://engineering.careers360.com/articles/nits-cutoff-for-top-btech-branches.

Best of Luck.

Hope this helps.

Cheers!
