Hello Arpit. Your rank would be somewhere around 13000-14000. Based on your you have a very good chance of getting CSE in colleges like KLE Technological university, Sapthagiri college of engineering, Vidyavardhaka college of engineering and other colleges. I suggest you check the last year cutoff for every college and finalize which college you will apply. Below is the link to the COMEDK cutoff:
