> Only by getting feedback from real students can you truly figure out whether a textbook is good. The problem is (also in my experience) that students often cannot grasp the depth of the textbook/topic when they here the lecture. I openly admit that I only could appreciate the depth of the topics taught in some math lectures 5-10 years later (but already at the time that I heard them, I loved hard lectures - in oppposite to many classmaters). So if you want to get feedback, ask the students not before 5 to 10 years after they heard the lecture - otherwise the answers will in my opinion be meaningless.
