So I have successfully transfered to a 4 year university from a community college. I am majoring in mathematics. I have completed: Calculus 1,2,3, Introduction to Ordinary Differential Equations, Introduction to Linear Algebra, Introduction to Discrete Mathematics. I have also completed introduction to mechanics and electricity and magnetism ( Freshman physics sequence). I plan to double major in Math/Physics or Math/Aerospace engineering. My school offers a joint Phd program with Claremont Graduate University. The Phd is a Doctorate of Philosophy in Engineering and Applied Mathematics. This is something I seem interested in, if I double major in Engineering. However, physics is something I am interested in. Anyhow, in order to double major, I must complete the last introductory physics course and 2 semesters of general chemistry. I am definitely going to take the last introductory physics course. My question is, should I spend time taking the 2 chemistry courses? I have never had a chemistry course. I feel comfortable with self learning mathematics, and I can study for these 2 classes and pass an examination to receive credit. Or would it be more beneficial for me to actually take the course?
