Hello aspirant,

The eligibility for appearing for UGC NET are:

--> You must have to complete post graduation in any stream with an aggregate of 55% marks and without rounding off.

--> The age limit for JRF is below 30 but there is no age limit for the post of Assistant Professor.

--> You can apply for the UGC NET Exam only for the subject in which he has completed his master's degree/equivalent. But in case, the subject is not on the list, he may apply for the related subject.
