It's even worse than that--the first edition only contains *one* test, the second edition only *two* and the third editions has *three*! The fourth test is provided free online by ETS. And yup, there's no review material whatsoever.
I'd advise against the 'purple book' ('The Best Preparation for the GRE Physics') for anything more than a starter refresh course; it has some good practice questions but also a lot of typos, some very poor questions, and a very incomplete review section.
There's a huge section on this website for review books...and if you haven't discovered it yet, do try out:
It has the best test-specific prep material I've seen: worked solutions to all four tests plus advice on guessing if you're short on time. Very test-specific!
