Dear Sahil,Great! You have passed the criteria for PCM total.Now Nagpur is your home university and your caste is OBC.Hence look for GOBCH cutoffs for the colleges under Nagpur university & GOBCO for colleges apart from Nagpur University. You can also look for GOBCS for state-level seats.Based on your marks and previous year cutoffs here are some decent colleges that you can look for CS branchAnkush Shikshan Sanstha's G. H. Raisoni Institute of Engineering & Technology, NagpurRajiv Gandhi College of Engineering & Research, Hingna Road, NagpurGondia Education Society's Manoharbhai Patel Institute Of Engineering & Technology, Shahapur, BhandaraDatta Meghe Institute of Medical Science's Datta Meghe Institute of Engineering & Technology & Research, Savangi (Meghe)Lokmanya Tilak Jankalyan Shiksan Sanstha, Priyadarshini Indira Gandhi College of Engineering, NagpurMatoshri College of Engineering and Research Centre, Eklahare, NashikGokhale Education Society's, R.H.
