Dear Rahul,
As you mentioned about the University kindly mention in the comment box the name of the university so that I would be able to guide you in a more accurate manner.
But as per rules , if your classes are going offline with full fledged strength then only don't think your fees would be decreased.
But as many colleges are still online it is quite possible that your fees may be reduced due to the online classes as their should not be any hostel fees and mess fees.
On the other hand these things totally depends on the college administration on what they are willing to do.
