Where do I start learning chemistry? I'm an adult male in mid 20s who didn't learn shit about chemistry in school. I'm smart enough to learn, I just need the mateiral. I want to cover the basics and then venture further. I think I'd like to learn about polymers.

Basics should be easy to cover with basic school text books/internet, but where do I find higher level stuff? Do you have any good resources, youtube channels and so on (I know cody's lab)?
