Few buildings - just a few minutes between classes. Learning is directed more toward the classroom environment, rather than based on outside studying or homework, due to the large amount of time spent in class and sometimes based on effort, instead of academic grades or other measurable standards of performance. Parents are usually supportive or demanding, helping to ensure completion of studies and providing security. Friendships have developed, perhaps since grade school, which help satisfy social and interpersonal needs. Time management in high school is often easier than in college.
Students usually have more time for activities outside of class, less homework.
Students may have breaks between classes of one or more hours, or may even choose to take night classes. Colleges are big places with many buildings spread out over acres of land. It is sometimes tough to get to the next class with only a few minutes in between. Instructors and teaching styles are amazingly variable. Low personal attention is provided by faculty.
