As an undergrad pursuing a bachelors in physics, mathematics or engineering; how many hours do you spend on your homework? And if you've already graduated, how many hours did you use to spend on your homework? For example, how many hours would you study for classes such as the following? And if you've already taken these, how much studying/homework did you do day per day per class? Calculus 1 Chemistry 1 Physics(classical mechanics) programming class. I realize people are different and that some people do need to study harder than others, but with that in mind, let's just say in general.
