Dear Esha!

The admission process varies form college to college. Some colleges conduct entrance exam and then on the basis of that score , they ask you to fill the application form of that particular college. In other cases, after an entrance exam, you have to register for counselling instead of filling an application form where you will have to fill all your choice of colleges from given choice. The counselling conducting body will further direct your the way for admission. Some colleges even don't conduct entrance exam and that college you have to just fill the college admission form. So, it just depend on the college rules.

Hope this will help you.
