> This is not bad advice

I was going to say this article was a bad advice.

I second the solving problems approach. It's pretty mainstream opinion really, at least among math/phys students. You can try to follow the article and feel you "understand" the topic. And still unable to solve any of the homework problems, let alone exams.

Reading is necessary but insufficient, but you can at least make it efficient -- that's what the article is covering I think.
