Query: This is a HORRIBLE book--DO NOT BUY IT!!!!!

This book was used for one of my undergraduate abstract algebra classes.The book is just as difficult to understand as a more advanced, comprehensive abstract algebra text, but it is small, and leaves out lots of material, glossing over difficult proofs and leaving out important topics.The book also has some serious flaws in major proofs--notably, one in the proof that solvability in Galois groups corresponds to solvability in polynomials.The overall reason for complaint however is that the book is not clear. It claims to be usable for a "first course in abstract algebra" but this claim is completely absurd--it was my second abstract algebra class and I still had trouble with the book. I had trouble both because it said so little, and because it said it so unclearly.DO not buy this book--make a decision, based on your background and buy:(1) An easier to read book with better explanationsOR(2) A more comprehensive text.Trust me--you'll be better off!
