Hello Vansh,

Well if you want to take admission in NIIT University, you first have to clear JEE Mains cutoff as NIIT takes admission through JEE Mains score. Below I have provided 2019 JEE Main cutoff (percentile) category wise - 

• CRL : 89.75
• GEN-EWS : 78.21
• OBC-NCL : 74.31
• SC : 54.01
• ST : 44.33
• PwD : 0.11

Now as per your rank in JEE Mains, you may get a seat in NIIT University but in which branch will you get that is hard to say. For that you must attend the counselling proccess to see which branch do you get. The counselling process will be handled by JoSAA. You may not get a seat in the first few rounds , but you might be able to get a seat in the later rounds of JoSAA counselling. Also, apply for other college too to improve your chances.
