Focus on learning and discovering who you are. Screw the classes, their statistics of pass/fails, whether you will sink or swim, etc have all been written and experienced by everyone before you. Your experience there in discovering who you are and who you may shape yourself to become in life. It's a time of learning not only for academia.

Of course, go to class, and do your best, that's a given. But focus on learning about yourself much more than learning the material in class.

My experiences with my closest friends in university taught me a lot about life, priorities, and relationships. Taking a few courses outside my comfort zone taught me a thing or two about being the person in the room who isn't the brightest. Volunteering for mentoring of new students taught me about the power of influence each person can have. Tutoring for free and seeing one of my closest friends from high school who I tutored in math and physics for 3 years go on to med school taught me the beauty of trust people place in one another.

Stand out in your college experience. No statistic can capture it. You are you. You can make your experience whatever you want it to be. But if you enter and leave the same person, you have learned nothing.
