High schooler invited to PTK Honor Society

I’m in a dual enrollment program- taking community college credits while in high school. I got the invasion by email. I read it and still have no clue what it is or if it’s worth it: there’s a $65 membership.

Anyways, what’s it like? Is it a huge commitment? I am overloaded with both HS and CC this Spring semester so I don’t know how PTK would fit in or make it worse.
