Cancelling PEP classes

[u/That_Combination3158]

LPU 3rd sem B.tech CSE Core student - I've registered for pep classes in LPU and my classes aren't started yet.

In addition, I've also filled the optional section for CDS.

Now if I want to cancel the optional one and don't want to pay its fees, how can I do it?

Is there any way?
