Greetings aspirant!

It's hard to find good universities without minimal registration fee. However you can opt for government universities for their registration fee is much less than most private universities.

For example :- delhi university charge minimal amount of 180-200 rupees for it's registration form and their are so many reputed colleges for B.com under DU.

If you have any particular university in mind and want to know about it's registration fee, feel free to ask.

Hope you find it helpful.
