A question to all my fellow alumni.

I've been out of school for 2 years now and I can already feel my brain starting to rot even while practicing in the field I've studied in. Everything feels muddled and starting to run together like a greasy paste.

My question is that if you're school you graduated from will let you sit in at classes to basically refresh material you studied in?

Has anyone tried this?

Have you tried doing this at other schools without enrolling and do they give you shit?

Any experiences on this?
