Hello Anurag,

With a rank of 2820 in the JEE main in the EWS category and if your state is Telangana,it is a decent rank and you will get some or the other branches in the top NITs.But as you have told that you are interested in the NIT warangal,you won't be getting a computer science or the ECE or the electrical engineering branch in the Institution because the reservation given to EWS category is very less which is just an extra 10 percentage.So you can try for a mechanical engineering branchs.You can use the following careers360 college predictor to know more about the colleges and the branches you will be getting into.Hope this answer helps.Thank you.
