Query: Terrible

Disregard the positive review. This book is a nightmare. There's aren't many defects I could point out that the other reviewers haven't done a good job covering already, other than to say they're dead on. Perhaps the only thing I could add would be to say that if the Chinese department at the school where you take classes still uses the PCR series, you should seriously consider a change of major.
