Hey!
Let me shock you with 3 things about the university you didn't probably know. As a matter of fact, many people don't know them until they graduate from school and suddenly begin to wish they knew these things and consciously apply themselves while they had their time within the four walls of the university.
Human Networks: For most people, the university community is your last chance to meet people who you'll really know for who they are in life (that's apart from famiky etc..). People who will work with you, who will form a large base of your networks, probably someone you'll marry in the future, which is closer than ever now.
So I think you will like to carefully choose friends and see to it that you treat people right.Career: As straightforward as this may seem, it may turn out different for many people. I know you must have heard of people read Education and ended up working as a banker. The thing here is virtually all of us has the capacity to steer our career in the direction we want. For instance, most people who are tech gurus and those who are motivational sprakers didn't study related courses in school. So you really still have the power to make of your life what you want with it no matter the course you've been admitted to study.
Investment: Invest in yourself by reading self development books, learn something, invest in your social life( to an extent that its dafe for you). Invest in your enterpreneurial mind.
Most people who made it big after school, laid the foundation when they were in school. Don't waste your time and opportunity. Maximize it to the fullest!
