Hello student. 577 rank is a pretty good one for you to fetch a seat in computer science in coimbatore. The cut off for computer science last year went till 1900. This is the closing rank for computer science in open quota.

So this year, the closing rank might definitely increase since it depends on number of applicants, the number of students attending counselling so on and so forth. you will definitely get through. When it comes to other campuses like banglore or kerala, you have a higher chances to get computer science.
