[0] Studying [High School] You may study outside of class as little as 0 to 2 hours a week, and this may be mostly last-minute preparation. You often need to read or hear presentations only once to learn all you need to know. You are expected to read short assignments that are then discussed, and often re-taught, in class. Guiding Principle: You will usually be told in class what you needed to learn from assigned readings. [College] 
You need to study at least 2 to 3 hours outside of class for every hour in class – this equates to anywhere between 6-45 hours of study time outside of class per week. You need to review class notes and text material regularly. You are assigned substantial amounts of reading and writing that may not be directly addressed in class. Guiding Principle: It's up to you to read and understand the assigned material. Lectures and assignments are based on the assumption that you have done this.
