Most classes meet only two to three times a week. Even though classes meet less frequently, college students are responsible for learning much more material. Because of that, college students have to put in a lot more study time than they did in high school to get the same grades. Ask any successful college sophomore or junior. Most students have gaps in their class schedules.
Students sometimes have evening classes as well as early morning classes.
As you can imagine, one of the biggest challenges freshmen face is learning how to manage their time. You will have more choice in setting your schedule. Although there are many required courses in college, you still have more choice than in high school about what courses to take and when to take them. You also have choices to make about how to organize your weekly class schedule. Some students prefer to schedule three or four classes back to back without a break.
