Hi, Himanshu. 

In Madan Mohan Malviya University, the cutoff is always based on how hard the paper is given as if the paper is hard, the cutoff will go down. If the paper is easy cutoff will be high.

As you are expecting 180 marks, you'll be under the ranks of top 800.

As of 2018, cse branch closing rank for general category boys i.e, GNOP is 734

Hope you'll get in, 

All the best
