Oh man, so this is an actual problem? I've had this a lot as well, but I only have it with numbers and with multiple choice tests. For example, if I'm given a reading passage, I can accurately answer questions about it. But once those are put in A/B/C/D or 1/2/3/4 options, I will absolutely mess them up. I will know the answer is A, I will put my pencil down on the A bubble, I will fill in A, then later on I'll see that somehow I filled in C. I had this problem a lot on tests and thought that maybe I was just being dumb and not having the correct answer, since usually you only get a scantron sheet back with zero context. About 3 years ago I started doing practice tests for language learning, of which many questions were multiple choice. I'd write the full answer for extra practice, finish the test, wait a couple minutes, then go back and check my answers. The written part of the answer would match up most of the time. The letter/number preceding it was wrong 1/4 of the time. I've also had it with math exams a few times, where I mix up digits usually around decimal points. Sometimes it even happens when coding and those are really tough problems to debug.
