Josephine, I don't see a single probabilities or differential equations course in that list. You better take some of those.
I did actually took a class called Statistical Models/Methods. It is a calculus-based statistics class and it is the pre-req for my Econometrics class. I learned pdf, poisson, regression, conditional probability, and some other stuff that I do not remember. Did some T-test, F-test too.
I guess if that's not enough, I should take a higher stat class, Intro to Probability. That will dwell deep into probability topic.
As for differential equation, I don't take the class because I'm a grader for that class. I have to correct students' homework, so I guess that should be fine?
