True, no worries then. Hmm I guess maths B may help but I don't think its really necessary (I had done it in high school though, and it certainly helping with the exercise science component of my course). Having done chemistry would definitely be a helpful factor, that being said, I managed to do very well in Chemistry despite having not done it in high school. But Im still yet to do Biochemistry and Molecular Biology in my course which will likely be quite hard. Be warned, I worked really really hard to do as well as I did in Chemistry, its definitely not an easy thing to get your head around, don't expect to just cruise through. Then again, if you really want to do nutrition, you'll get through it I'm sure, especially once you start linking the stuff your learning to real life applications of nutrition. What uni are you planning on going to/what area are you?
