I think I saw somewhere that for you to be a SWO on a nuclear ship that you need those classes. I just wanted to see if that was certain. Also how hard are they? I've only gone up to Alg. II and passed with a 88 or something like that. I know I want a major in something but it requires theses classes and you need a 3.0 or higher to have a good chance of getting in so are their any tips on getting through calculus or is it if you have it you do and if you don't your just out of luck?
