Dear Aspirant 

Kindly check college or university under which your college is. There you must have been informed that you have to visit on particular date to get your documents verified and to fulfill remaining criteria for your admission. So don't check website, contact your college.

Good luck for your future :) 

Feel free to ask if you have any further queries.
