For a lot of people, college is like stepping into the world of time management. Unlike your high school days where you stay in school for hours going to class after class and then attend a club, college is very different. You get to pick your classes, your schedule, and you have more unstructured time to yourself.
But also unlike high school, there can be a lot of distractions in college, not to mention the number of parties you get invited to. Usually, students' social lives are more exciting which can also take a toll on their health apart from the already heavy load classes are giving.
