Attend all of your classes. This might sound obvious, but each class you skip costs hundreds of tuition dollars. Even if the professor posts the lecture notes online or you already know the material, attending class engages your brain and exposes you to discussion and different viewpoints.
Meet with your professors and academic adviser for individual attention. It's easy to get lost in the crowd at a large school, but even in a smaller educational environment, you need to initiate the personal contact for which you're paying. Rarely in life will you have access to so many educated and intelligent people whose primary purpose is to teach you.
Visit the college's career services center regularly. Landing a well-paying job takes footwork and persistence, and the career center is the best place to start. Private career consultants charge hundreds, if not thousands, of dollars for services such as resume review, interview critiques and networking resources. Many college career centers provide these services for free, so use them often to seek out internships, fellowships and, eventually, a job.
Join extracurricular activities. Activity fees, sometimes listed under "other fees," are part of your tuition costs. The money from these fees pays for everything related to extracurricular and co-curricular activities, such as travel accommodations for the debate team, music for the choir and studio fees for the ceramics club. Get the most for your money by joining several activities. You can drop one or two later if you get overloaded.
Use the school's facilities frequently. Your tuition dollars help pay for those glassy fitness centers and state-of-the-art computer labs. Not using your school's facilities is like paying for membership in a gym that offers spinning, yoga and strength training and then only running on the treadmill.
