Test discussion, and propositional variables

I think the test went well? It's difficult to say. It was one of those tests where at no point was answering anything problematic in some way, and at no point did I run into something that looked like it could have been an error ... but at the same time I'd feel genuinely queasy claiming I aced it. Maybe I'm just being superstitious. At any rate I think I'll have to see what happens when it gets returned.

Not finding structural induction on the test made me a bit sad, which might be because I'd focussed much of my studying on structural induction because a part of it still kind of eludes me. I'd done a bit of studying on this because I feel like it's one of those things I "understand" but don't fully understand. Superficially, it's pretty simple to just say that structural induction is just a little more abstract a version of the other induction flavours we've seen. But I think that explanation is - in addition to being a little too vague - eliminating the question of what is a propositional variable anyway.

So there's this test tomorrow...

I don't feel like I've studied enough but at the same time I'm unsure how much more I can prepare. I understood the lectures, I've read the notes a few times now, and I've been doing practice problems and still I feel like I'm really not that well prepared for it. Maybe looking at some past exams will help me convince myself I'm prepared?

It might be because this past weekend got eaten up by another class's assignment, and today got eaten up by work and studying for another class's quiz. (Taking this many courses is difficult without also working, but combine working and it's a bit much.) I don't know, I guess I'm just used to studying for midterms by devoting time directly before the midterm, and because the time has been stretched over different days in different weeks, it feels like it's not enough, even if it's the same amount of hours.

It might also be because I found the assignment easy (long, but easy). As in, I was expecting it to be super gruelling and challenging and impossibly difficult, and was surprised when it actually wasn't all that bad, really, and I was able to do it on my own. Well, I say this now, but the marks haven't come back yet.

I guess we'll find out tomorrow.
