Firstly, learn how to organize yourself. You're gonna get bombarded with assignments and projects (that are so much fun!..), and if you don't have a way to organize everything you may start to slowly lose your mind (trust me, it'll happen). Make sure you have a 'To Do' list with assignments listed by priority and a calendar with all your due dates! You really don't want to have that feeling of blood rushing to your face when a prof asks for an assignment that you completely forgot about..
Secondly, be open-minded. You'll be working on many different projects with many very different people. Being open to other's ideas and perspectives will only help you build great ideas.
Thirdly, take advantage of every opportunity you can. Whether it's a career development session or an advertising competition, try to immerse yourself as much as possible. You'll make new friends and have experiences that will help you find a job when you're done the program.
Fourthly, take your studies seriously. You're in this program for a reason... to get a job. If you half-ass your assignments you'll be wasting your time and money, and that is just a silly thing to do now isn't it.
Fifthly(?), sass Colin Robey as much as humanely possible. He'll probably be your program coordinator and he loves it when people make fun of Media or don't laugh at his jokes. Doing these things will secure you as a fanTASTic student in his books.
Sixthly(?), have a great time! Taking this program was the best decision of my life. The classes are excellent and the profs are super personable and willing to help you in any way possible (not to mention, they know what they're talking about).
That's all the advice I have for now. I hope this post helps you make the decision to come to Sheridan for the Advertising: Account Management program and enjoy it while you're here!
Cheers!
