Maybe this has changed in recent years (doubt it), but scuba diving in Mexico has historically been about a 30 minute course on how not to die, then you jump in.
I was certified way back in college, and if you're just looking for an afternoon of diving, it's quick to learn. It gets complicated when you're talking about diving over the course of consecutive days with nitrogen build up.
