College is more than studying to get a diploma. Readings, homework, and requirements are only half the battle. There are things you need to know about college that even college professors won’t teach you. Among all the college rankings that you are obliged to check in order to set your priorities or the tuition fees that you need to know in order to save money, there are other things you need to know about college, so be prepared.
    First of all, you should be aware that BFFs (Best Friends Forever) will not be formed overnight. Most of you are eager to make friends. Some people you meet will only be classmates, acquaintances, or report partners. Finding your close-knit group in college takes a bit of trial and error. Join student organizations and interest clubs, attend a few parties, and enjoy the variety of people you meet along the way.
    Next, you have to get to know your professors well. Professors can make or break you, so don’t stay in the dark. Check out student forums for professor guidelines and tips. Build a professional relationship with your professors.           
    Moreover, you should be creative, as books are expensive. A study reveals that every year, the average American college student spends up to $1,200 on books and supplies alone. Save some money on books. Borrow from the library, visit a second-hand bookstore, ask friends to lend you a copy, ask your professor if he or she has a spare book you can use, rent a digital copy, or shop online for used textbooks.
    In addition, you have to figure out that required reading can be optional. This is entirely on a case-by-case basis that you need to figure out. Generally, professors will discuss the most important points of the text in class. When you pay attention to lectures and diligently take notes, you can get away with just skimming your readings before exams.
    Last but not least, sometimes you need to isolate yourself to get things done. Distractions are everywhere. When you have a paper due in a few hours, isolation is your best bet at finishing on time. If you have references online, download them and turn off your WiFi connection. Stay in a library instead of your dorm, so you’re not tempted to take a nap.
