Hello aspirant,

For availing of the sports quota in NEET, a candidate must possess any medal (or participation) on a district level, national level, or international level.

Preference is given to those candidates who have won National level medals in SUPER A games or B games.

Super A games include Olympic Games, World Championships, Asian Games, and Commonwealth games. B games include national games, national championships, All India Inter-Zonal meets, etc. A gold medal will also be prioritized over a silver or bronze medal even if they are more in number.

Hence, since you have a national-level certificate, you will be eligible under the sports quota of Tamil Nadu.

Hope it helps!
