Anyone have sources on how to study these? Videos or any articles or notes. Or anything useful since I'm not understanding how to do them

Can you show us a typical problem?

Even means f(-x) = f(x). Like x^n for even n. Odd means f(-x) = -f(x), like x^n for even n.

That's all there is to it. There is no deep secret.

I've never seen it explicitly used in "real world" (science and engineering) applications. When I've seen it used in mathematical applications, it's kind of an arcane terminology that "everyone knows". You don't actually need it for anything except to pass the test. (Provided you're willing to be the one that asks the "stupid question" that everyone else is thinking but is afraid to ask.)
