Obviously, it is important to work lots of problems when learning math and physics. At the same time, it's useless if you haven't learned the material from reading the textbook sections. I can see two extreme approaches to studying out of a textbook. The first is reading the textbook extremely diligently, understanding every single word and then not working any problems. The other is not reading the textbook at all and skipping right to problems and working them all. What do you think is the best balance between these two extremes when studying out of a textbook, especially when trying to keep up with a fast-paced course? I haven't quite figured out what works best for me yet, so I'm very interested to hear what works best for you. Thanks in advanced.
