This textbook has a lot of good information on the topics it teaches. The problems for assignments are also good, because each chapter includes review problesms, so you don't forget skills from previous chapters.
However, the majority of the conjectures (and by majority, I mean all but maybe one or two) are not filled in. This textbook was designed for students to "discover" the conjectures themselves, which makes this an awful textbook for teaching yourself, or taking notes. The "fill in the blank conjectures" make math class worse.
