The fee structure for CSE through management quota was Rs. 7 lakhs per year for the last year (2017). It was Rs. 6 lakhs for the year prior to that (2016). The fee is expected to increase this year too. For the other branches, the fee is lower by 1 or 2 lakhs.

No, the PES University Main Campus doesn't take admission via COMEDK score. Now, the college conducts its own exam PESSAT. You can also get into this college via KCET.
