big blue book (premier program) is the exact same, word for word, stuff that they give you when you enroll in the kaplan course (the white books)
ive heard people say that they were carbon copies before, and i compared with a friend enrolled in the course today. i believe however that the white books have more questions.
the organic chemistry seems more in depth than the EK books. and as for verbal theres not much, but then again no book really has a lot for verbal.
in any case, the book is fine. i am using it as my main book (with EK complete package as secondary), and although there are a few mistakes here and there (every book has these, hello?) it's not like the mistakes are blatantly wrong concepts like f=mv or something ******ed.
it's not a god awful book as ryserr posts, i know a friend that used that book exclusively and got 98th percentile. so yea :/
everyone criticizes everything, people have preferences, take it all with a grain of salt.
