Dear aspirant,

To study in any college you will have to secure seat in that college. Every college has few exams which it considers for taking admissions.

One such exam is PGCET. Hence you have to attend the exam and fullfil the requiremnts provided by the Institute in that year to secure seat. Usually 40% aggregate will make a candidate qualify and every institution will again keep another cut off for various branch, category.

Hope this helps.

Good luck.
