Hi

Is 14212 your AIR or SC Category Rank? If this is your AIR, then it is very astonishing you did not get NIT at this rank, when this rank can fetch you even CSE at few NITs and GFTIs.

If this is your SC Category rank, then you have low chances to get any branch at any of the leading NITs. Though you can expect to get North-East NITs, definitely not the trending branches. I'm sharing the link below through which you can check your probability of getting NITs and other branches.

You can always check this link to know more 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!
