For reasons I won't get into I was forced to leave school for the work force very early. I got my GED when I was 20 with a very high score, but now I'm trying to join the Canadian Military to take advantage of their University subsidy program. They do not classify the GED as a full grade 12, so I will be forced to take the required courses before applying. The prerequisite programs are English ENG4U Advanced Functions MHF4U Calculus and Vectors MCV4U Chemistry SCH4U Physics SPH4U and 2 Mathematics. There are so many mathematics courses to choose from, which do you recommend for Mechanical and Aerospace engineering?
