Review title: Kittel's book very hard to learn.
Product review: I dislike this book as an undergraduate student, because Kittel knows the material very well, but is unable to communicate the subject in a pedagogically sound manner. There are many steps missing from his proofs, there are no answers in the back of the book, and the problems themselves are difficult to begin. Kittel does not usually make it clear what a problem is asking. My advisor chose the book because of its organization, which is good; yet he also admitted the difficulties above mentioned.
