Hey Byamini! Special category certificate (like NCC/ PH/ Sports/ CTS etc) are accepted. TS PGECET or Telangana Post Graduate Engineering Common Entrance Test is a state level entrance exam administered by Osmania University, Hyderabad on behalf of TSCHE.

EBC is Economically Backward Class with this quota you get little relaxation in fees, but according to my knowledge there is no reimbursement for EBC quota. Hope this may help you.
