I just realized while going through old problems from the exercise course again (something I didn't do first time - huge mistake, because apparently about 50% of the problems were related to the exercises. woot) that I did learn something; revisiting old problems, in many cases I can actually get to the solution a lot faster than on the first try, and they don't seem as complicated as I remember them to be (most of them, anyway). So that's probably a good sign, and might mean that I kinda understood the basics?

So yeah, I did learn something, and nobody can take that away from me, even if I do fail that exam tomorrow. Again. Which would be hilarious because I have no idea how much more I could do.
