Hi Pradeep ,
Greetings!

Please be more specific about which entrance exam are your reffering to?
Then only I will be able to answer this question .

However , the prodecure that nearly every college follows is first you have to fill the application form to sit in the entrance exam and after the results are declared - a merit list will be prepared followed by counselling process in which students will get colleges according to the rank that they have secured in the entrance exam.

Hope this helps. Good Luck !
Revert back if you have any more queries.
