Hi, is it a bad idea to take Intro to Linear Algebra Vector Calc for Applications (Marsden) Intro to Probability (book called first course in probability by ross) .. in the same semester? This semester I took discrete math and Calc 1 at the same time and it was pretty time consuming but that is partially because I like to spend a lot of time "playing around" with problems and concepts in the books that were not covered in class; making up problems etc. The vector calc class is mostly for engineering majors but I feel it would help me prepare for the class "marsden basic complex analysis" for which ODE or vector cal is a prereq. (I took ODE in summer school a long time ago and forgot it all) Many people recommend taking no more than 2 math classes per semester and I agree because I like being able to devote a lot of time getting comfortable with the material (asking supplementary questions in office hours and such) but what do I fill the rest of my schedule with? I already finished the general education requirements and I'd like to spend most of my studying time on math rather than some filler courses that I put on my schedule just to remain a full-time student but it would not be plausible at all for me to have 4 math courses per semester especially as i get into harder and harder math.. So what to do?
