Hello Kiran, In 2018 the cutoff for CSE was 18432 after the 3rd round, in 2017 the cutoff was 23293 and in 2015 it was 26535. Can't say for sure what will happen this year but you sure should apply in case you get selected. 

Kiran, 

Last year cut off for various branches in NU was

Chemical Engineering 33346 

Civil Engineering 37834 

Computer Science and Engineering 18432 

Electrical Engineering 33019 

Electronics and Communication Engineering 27221 

Instrumentation and Control Engineering 35577 

Mechanical engineering 29073

Though it may seem that you won't get CSE but the closing ranks I have Provided is of round 3 but I am quite confident you will get CSE in NIRMA UNIVERSITY in spot round no need to worry.  

Hello Kiran

Last year the closing rank was 24k for CSE and last to last year it was around 26k. So, your rank lies between them. I believe in the first two rounds you will easily get into all branches except IT CE ME. But be patient in the third round you may get IT.

Chances are high.
