Query: Good for questions, little else

Why can't someone make a good chemistry GRE review book? This one is rife with errors, obsolete questions, and has the test format wrong (too many questions per a given period of time). The answers are helpful, but for many I ended up having to look them up anyway. And when I say errors, I mean many errors which will have you scratching your head to answer a question only to realize the right answer does not exist, as it is obscured by a typo. Occasionally their answers are scientifically incorrect as well.That said, this book has some value, but mostly if you've already reviewed the material and are simply looking to practice.All and all, it might be worth the money to have some extra practice problems. But this book is good for little else. You'll need textbooks.
