Hey, I'm a 0L as well. I have read Getting to Maybe, and I just got leews in the mail. I haven't done the whole program yet, but I've looked through the primer and read some of the introductory stuff. I thought Getting to Maybe was fine. Lots about issue spotting, "forks in the road" in terms of gray areas in the law and how to spot them. It does talk about how to write exams, and gives alternatives to IRAC. I certainly enjoyed reading it (it's an easy read), and I thought it put some good ideas in my head.
It's definitely not the same thing as leews though. Just from what I've read in the introductory materials and what I saw in the primer, leews is much more hands on, and comprehensive in terms of teaching you how to write exam answers, and how to prepare for exams all semester (how to brief cases so that your briefs are geared towards potential exam questions, etc). I don't know if I'll follow the system to a T, I usually end up doing my own thing, but I really like that leews really teaches you, and makes you practice, their system. If you're going to either read Getting to Maybe or do Leews, I would do Leews, but get the cds, I think that's better than a one day class.
