Hello Raju Onkar

In Bangalore, you won't get the top 10 colleges even if you have reserved category status for computer science. You might get MVJ college, Sir M.Visveswaraya Institute of Technology if have ST/SC status. For general category students you can get Ghousia Engineering College,Dr.T.Thimmaiah Institute of Technology, Kalpatharu Institute of Technology etc. in CS.

For reference, you can see KCET 2017 cutoff : https://images.careers360.mobi/sites/default/files/KCET-engg_cutoff_gen-round-1.pdf

Hope this will helpful

Good Luck...
