Practice midterms fixed

It was brought to my attention that there were some problems with the practice midterms I’d posted.

One such problem was that one of the keys didn’t match the test it was supposed to. Another was that, once it did match, some of the answers were not right, they referred to questions in other tests. I have a couple of hypotheses about why that happened, but it doesn’t matter. It has I think been fixed.

Do let me know if something doesn’t seem right, of course, thanks to those who pointed this out to me!
