Cancelling my AP Exam

yo guys i don't want to take an AP exam, so should i pay the late fee or just not show up? i know i haven't studied and i don't really care too much about not getting credit for it either, it's just unnecessary anxiety rn. are there any consequences to just skipping?

Edit: ok wait can i take AP Physics C mechanics and not take the Physics C E&M exam? i don't feel confident at all for E&M
