Hello

IIIT Hyderabad offers admission to the Undergraduate courses on the basis of following modes-

Undergraduate Engineering Entrance Examination (UGEE)

Special Channel of Admission (SPEC)

Olympiad

Lateral Entry Entrance Exam (LEEE)

There is Special Channel of Admission (SPEC) for students with extraordinary talent or background. But, I don't think there is any Sports Quota.
