Hey. Was wondering if anyone had used this or had any feedback on whether this book was any good. I am having a slight schedule conflict with advanced calculus next semester and was considering taking topology. They use this book. On Amazon, there are only 2 reviews which are at opposite extreme ends of the spectrum. If the book is good, I may go ahead and take the course, if it's not, then I may just have to be 15 minutes late to class every day so I can continue studying Rudin for another semester.
