More reading. And having fun with school. Apparently I'm not very good at understanding the structure of an expression, since you have to get 5 questions in a row right in order to pass an exercise, but I get literally every other question wrong. Some equations I can figure out, but the others I can't. I'm working a lot at this. Other than that, nothing much.
