Hi, I'm a freshman undergrad and I want to declare major in physics. Even though the department counselor wants me to take 1 math classes at a time, the summer schedule doesn't really fit together since one math class has a time conflict with another physics class (plus I'm being stubborn). I also want to take some graduate courses later on if I finish fast. So I'm wondering, is it okay to take: Calculus of Several Variable (Part B), Linear Algebra and Application, and Differential Equation at the same time? They're all in engineering and physical science math series. My school has a quarter system (10 weeks + 1 Final week). Together they're 12 units, and if I add one general education course, they'll add up to 17 units; that doesn't sound too bad for me. Probably I will be stressed out facing math all the time, that's okay with me. I can do other stuff to blow up my engine. My main concern, however, is my understanding of the subject. Will it be the same as taking it one at a time so it'll be build up over time? Your opinion will be greatly appreciated. Thank you. Note: I checked and none of them are prerequisite of each other. Although it says in the course description that taking Linear Algebra before Diff Eq is highly recommended.
