How much do you remember from previous semesters?

two semesters ago I took chemistry, history, and psychology, got an A in all of them, but I'm now realizing I remember next to nothing from those classes and it's starting to scare me. These classes aren't particularly relevant to my degree nor do the topics really interest me, and I know that you're less likely to remember something if you don't care much for it, but is it really to this degree? I feel like if I took the exams again I'd get an F all around. I hope I'm overreacting, is it normal to forget like this? I'd be scared of forgetting important things relevant to my degree as I progress through it or eventually get a career from it, with the latter scaring me much more. I'm curious how much you remember from previous semesters, both classes you really needed and cared about and classes that were less relevant
