No, just students who have to work harder at it than others. No big deal, you just have to put the graft in and get on with it if you want to master it. I don't think it's helpful to view yourself as having some sort of affliction, or to use it as an excuse - not that you necessarily are - just get on with it and beat it and the next time someone tells you you have 'dyscalculia' (is there such a word?) tell them they're talking bollocks.
By the way, after the theory exams you don't have to do very much number work at all - but don't tell anyone
