Your ideas about what a typical college class is like

 college schedule is that you usually have more opportunities to explore your interests and passions. For example, you will be picking a major that will determine the types of classes you will specialize in. In high school, you have a set curriculum of classes you have to take across all subject areas. In college, think about your schedule as a pyramid. Your freshman and sophomore year, you’ll take more general education classes (a mixture of everything so you walk away well-rounded) and a few classes in your major. But during your junior and senior year, you’ll take fewer general education classes and more classes in your major.Another big difference you should be aware of is the time structure. Right now, you’re probably in school from about 7:30 am–2:30 pm, Monday through Friday. This will not be the case in college, where you usually take four or five classes at different times throughout the week. You might have a science class on Mondays, Wednesdays, and Fridays from 10:10–11:00 am. Perhaps you’ll have a Spanish class on Tuesdays and Thursdays from 1:15–3:00 pm. Then, you might have your Introduction to Education class on Wednesday evenings from 6:30–9:00 pm. Maybe on Mondays you’ll have three classes, and on Tuesdays you’ll have two classes. There will always be some courses that are only offered on certain days at certain times, but for the most part, there are a lot of options to think about! If you’re a morning person, you might want to schedule your classes to be done by noon. If you’re more of a night owl, having that first class start at 1:15 in the afternoon might be the best thing to ever happen to you. And you definitely won’t be in class for seven hours straight!
