Ah. All things you definitely will not need calculus for, unless you're planning on becoming a high school math teacher. And thank god (no offense to Calculus, but I'm not into gym rats)
Psychology requires you to understand the series and basic differential calc, but that will be something you are taught within the course or as required units
I'm a psychology major and I have not heard calculus even mentioned in any of my classes or in any course description in the entire department. Is it a grad school thing?
