IIIT Hyderabad
IIT Delhi/ IIT Madras/ IIT Kharagpur
IIT Guwahati/IIT Roorkee
IIT Hyderabad
NIT Trichy
NIT Warangal
NIT Suratkal/NIT Calicut

Yes, you can apply for a management quota seat at RVR and the JC College of Engineering.
The management quota is also called Category B, and you can apply if you want to get admission to the MCA course at RVR College.
However, you will have to pay a higher fee to get admission into this quota. The Category B (management quota) fee for MCA at RVR and JC College of Engineering is Rs. 1.15 lakh per year. On the other hand, the fee for Category A ( allotted seats) is Rs. 38,400 per year.
Also, you may not get any scholarships under this quota.
The hostel fee is the same for both categories: Rs. 45,000 plus a Rs. 4,000 refundable deposit.

I appreciate your mode of selection in college. Yes you can get seat in Rvr and jc college go to their official website on google and fill admission form so that you can apply through online otherwise visit the college and get admission directly as you already wrote APICET you will be admitted in counselor quota and coming to fee they charge 1.0 to 1.6 lakh per annum.
