Not really.
I use to suck at spelling but with this, writing assignments and such I've gotten better.
Hm. Sorry that I keep asking questions. I'm just trying to get a better picture. So far from what I know you're not the best at math and you get fixated on math problems that then cause frustration and used to be good at chemistry, but struggling to pass now for some reason. There could be a number of reasons though if you're working hard already and still struggling perhaps there's something that isn't based on work?
