The (Not so Fresh-Faced) Student
Not sure why, but I seem to have decided to study astrophysics. I took a number of MOOC courses, and they were fun, but I wasn't really getting much depth. So I started working my way through a couple of books (and buying a bunch more). I quickly found that I really couldn't learn much unless I pretty much did everything - read every word, wrote down the equations and their derivations, and did the problem sets.
I didn't do that when I was a real student, but maybe I was smarter then.
