This is mostly adressed to those who has studied the book. I've heard a lot about this particular book and browsed it's contents. However, I would like to be certain whether I will encounter some facts I would have to take for granted or from other sources. From the preface:
This book was written with the idea that it would be used by students in their first year or two of graduate school. It is assumed that the reader is familiar with basic algebraic concepts such as groups and rings. It as also assumed that the student has an introductory course in topology.
Now, I would like to know how well one should know group and ring theory(and modules too, I assume? ) and general topology.
