I woulda learned how to use the search function. The topic of "what to bring to/how to survive your first 121 training evolution" is almost as beat to death as the "which flight case for the CRJ", "what kind of luggage" and "which headset do I need" debates.

But I'll second the car. Although chances are, at least one person in your class will probably have a car so depending on your situation it might not be worth the hassle when you can just make friends with said person with car.
