Hey Khanam ,
Greetings!

It varies from college to college as one of friend in b.pharm said..! If you want to get a better college you must get a good rank so that you may have a great opportunity to explore and learn more.
Kindly specify what do you mean by "free" seats ?

Good Luck ! You can reply to this comment if you have any further queries , I will be happy to help .
