First thing you need to do is to register the game. If you ordered through Origin, it may be already registered.
On the email I got, it says that the place to register both products is actually the same website and I got it to work but there are other websites being listed by trustworthy sources.
For the Origin Exclusive School Spirit Pack:
• Campus Cruiser: Get to your classes on time and in style on this sleek, modern scooter.
• Head of the Class: Your Sims can sport this classic, low-maintenance look that says they didn’t have time to do their hair because they were up late studying—or partying!
• “You Got Spirit” Face Paint: Get ready for the big game and make sure everyone knows your allegiance by wearing your school colors—on your face.
• Mascot Magic Face Paint: Some say painting the fierce, fighting llama on your face does not actually impact the outcome of the game. You know different. Do you want to win or what?

Partaeus Maximus will not only let you choose between toga, masquerade, formal, sleepwear, and swimwear parties, but will also boost the moods of all of your party guests.
