Common App "hell yeah?"

Can I say “hell yeah” in my common app? btw for context, it is NOT me quoting anyone else in my common app. I essentially say “hell yeah, I would.”

CAN you or SHOULD you? Yes, you “can”.

I don’t know how else to show my enthusiasm for this thing though? Like heck yes doesn’t carry the same weight? I pose a question and then answer it with “hell yeah,” do you think yes is okay too?

Okay, never mind I just did “yes, 100%” as my response
