The difference is a large number and it affects college students more.
In high school, homework is required to help motivate students to study.
In college most homework consists of studying; very little of it is written and turned in. If students do their homework, it is to their advantage; if they do not, the teachers will not force them to do it
high school students are less responsible; therefore, they need more guidance, which they can receive by going to class. In college, students may skip classes if they choose and refer to the syllabus to acquire missed assignments or tests. It is the student’s responsibility to make work up. In spite of these differences between high school and college, they both serve the same purpose -- to prepare an individual for the real world.
