So this is actually the 2nd time I am learning Ancient Greek. The first time I half-assed it and then got bogged down from carrying too many books. Now that I've got a writeable tablet, I am set and making good progress. I am using Mastronarde (again) and I figured that learning all the principal parts for each verb saves me a step really, so I am not just learning 3 and trying to shoehorn in the rest later. Anyway, I am having trouble. I get them mostly right (I'm on Chapter 5), but it's not quite sticking. I have used Smyth and Goodwin to learn the consonant rules and such, and those help, and I have read how Future, the Aorist, and the Perfect are formed and that helps, but it seems that there are as many exceptions or what could be mistaken as exceptions as there are adherents to the rules. Apart from just brute force memorizing and hoping it "sounds" and "looks" right when you write it or see it, any tricks to get you seasoned folks through memorizing the PPs? I am fine with the ol' keep-writing-them-out-until-your-hand-cramps and flashcards method, but I want to get a sense of scope before I take a deep breath and dive in. Thanks.
