No, It is not mandatory to have a sports certificate, however, students who have some experience in sports are given higher priority for admission.

If you have completed class 12, the duration of the course is 3-4 years and the eligibility is to clear 10+2.

If you have completed the graduation and you wish to get admission in BPED, then the duration of the course is 1-2 years.

I hope it helps.
