So I am an EE major currently taking Physics I and Calc II. Originally my plan was to take Physics II, Calc III, and Statics together with ODE and Circuit Analysis in the summer. A friend of mine made a point that ODE can come after Calc II rather than III. So now I have an option of switching Calc III and ODE. Now because all of these subjects probably share information (the math learned can be applied towards the physics) which order is the best. Is any Calc III used in physics II because I know ODE is necessary for Circuit analysis (its listed as a co-req) so it might be beneficial to learn it before I get there. How hard (relatively and in general) are Statics, Circuits, and ODE. I don't want to load all the hard classes together. Especially in a summer semester.
