Perhaps I'm missing the point, but I'm really skeptical that rote memorization of definitions is a sensible solution to this problem.
> For example, I recall that Epi and Mono are generalization of injective and of surjective. Or of surjective and injective. I can't remember which is which.
Specifically with respect to Epi and Mono, perhaps it would help to know that epi is from Greek meaning "upon" and mono is from Greek meaning "alone" (my dictionary tells me so), which immediately resolves the injective-surjective confusion example: Epi is surjective, Mono is injective.
