HI,

I assume you are asking about jee main exams, see to admission in iits you need to have the cutoff score in jee main to qualify in jee advance test, the you need to crack jee advance exam to get admission in b.tech courses in iits. now at this score you have very less chances for nits, since jee main april session is yet to held and if this time number of participants increased it would have effect on your current score. so try hard to bring good score in july exam.

you may use careers360 jee main knockout program to boost up your performance,
