If you have passed 12th from Tripura, then MAY BE YES… You may not get the more preferred branches like CSE, ECE, MECHANICAL etc., but you may get some of the branches which are less preferred. Through homestate quota, people get into their respective state NITs even without clearing cut offs ( I have seen cases). But if you are not eligible for state quota (not passed 12th from tripura) its a sure no… Hope you belong to first category… :-)
