I used to be pre-med but I switched to chemistry and I'd like to go to engineering grad school. I have to take more advanced physics classes in addition to chemistry but I've only taken the Algebra-based intro class. Can I take more advanced physics classes like Classical Mechanics, Modern Physics, or E&M without having to do the whole calculus-based introductory sequence? I should mention that I have also done very well with three semesters of calculus and linear algebra. I plan on taking DiffEQ next semester also.
