I'm signing up like, oh, I have a lot of gaps I can fill in with calculus, and it's like, no, you got a lot of gaps you need to fill in with simplifying cube root expressions. The best is every once in awhile it double checks to make sure I still know what multiplication is, with like Dick and Jane bought 10 apples problems. I have given it no reason to believe otherwise! But I trust the algorithm.
Also, I go too fast through them and do stuff in my head that I should write down and make dumb mistakes, and when I get the "Incorrect" I'm like, yeah, I see exactly the dumb thing I did, let's move on, and it's like, no, let's do a next problem that's real nice and easy to make sure you get this and I'm like "stop patronizing me motherfucker".
