I was debating between here and "General Physics", but since this is more about learning physics than the actual physics, here it is. I am currently a high school student and am studying physics and math on my free time. Since I've never taken an actual physics course, my general method of study is to read a book in order, and do most or all of the problems that have answers in the back, which generally amounts to about half of all the problems. However, I've noticed that the homework commonly assigned in college courses is much less, about ten per lecture. For example, when looking for solutions to Kleppner/Kolenkow I found that there were a few professors who posted them online for their students, but the total homework only amounted to about 100 problems per semester! This got me thinking, is my learning philosophy of "do endless problems" incorrect, or do university students actually do many more problems on their own, in class, etc. Or is there much more to physics than theoretical problems? I probably could understand the physics by doing less problems, but doing more doesn't seem to hurt.
