I am curious which math classes gave people the most trouble during their time in college. I am not looking for a "this class is harder than that class" kind of ruling as I know it differs from student to student and school to school. I am simply curious to see if there will be a pattern in the collective personal experiences. So for YOU the reader which class was the most difficult? Did they just get harder as you went along or did one stand out in the middle? Also just incase it proves to be different, which math class involved the most homework? Thanks for your response.
