Hey mani , i can not find any quota named convaer . Considering it to be convenor , i want to tell you that the reserved seats in convenor quota or management quota are called A Category seats. Seats in the convenor quota will be reserved in the following percentages - OC -50%, ST -6% SC -15%  BC-A-7% ,BC -B-10% ,BC-C-1% , BC-D-7% , BC-E 4%. The maim thing about convenor quota students is that their fees is least amongst all the other category studenyts . And , these seats are filled by the management .

Hope it helps
