Geez, this is kinda sad. A good amount of individuals I know [including myself] 'suck' at Math, the most lovely [ :roll: ] subject I've ever known. Throughout my years of being in school [i'm currently a Freshman]; I've always managed to pull off Math with a... B, save 8th Grade [best year ever; straight A's / A+'s], because I suppose our Arithmetic teacher was fairly lenient. But, anyway, on-topic-- you should worry about it [one would not get anywhere if he or she didn't], and explain the situation to your parents that it's fairly self-inflicted, if that was the case. My parents aren't particularly 'fair' when it comes to education [but at least I don't get flogged with a pointy stick if I don't get straight A's], but if they know about the grade and its 'whereabouts', chances are, the situation will improve. Maybe. Oh, and the school I go to is kinda lenient; 60% is a passing grade [a D], but, with the competition to be accepted into Universities nowadays, one might as well go to a Community College-- a big fat 'D' slaughters everything.
