If you are going to do a question bank as your means of studying (and honestly, the data on it seems to indicate that's probably the most effective way to prepare) I would suggest ROSH or PEER. Personally I really like ROSH. On the other hand, I stand by my plans of taking it blind, I would venture to say most will pass with zero preparation, with the backup of taking it the following year and studying if need be. Sure, you may fail, and you'd be out say 1500 bucks (or whatever it costs). But thats like a shift or less for most of us. I'd venture to guess most people are going to study far more than a single shift. So if you spend lets say 30 hours doing questions over several months, or maybe even more, then you would have spent like $6000 worth of earning potential time lost to studying. Financially, it makes more sense to not prepare and risk failure then spend too much time studying for something you'll probably pass anyways. Now granted, if you are in your last year of eligibility, I wouldn't do that. But if you have a backup, that'll be the strategy I take.
