Hello,there are 361 seats in sports quota under the purview of TNAU in 2020.In government quota if a candidate needs to avail sports quota he is not considered under other quotas like category or EWS.For  private colleges if he wants to go through management quota depending on the institution some preference may be given.For instance if you want to get into a government/self financing colleges through TNAU counseling you can get through only sports quota.But if you approach the institution privately for management quota they may put you under other reservation matrix too.Best wishes.
