A cute name for Physical Education. It's part of the core courses I have to take. Later on I plan on taking Adv Swimming since I've done the basic course (and I've been on a Swim Team before so I actually do know how to swim)
World of WarCraft does not use the Battle.net service which means your Battle.net accounts are different than your WoW accounts. To have a battle.net account, however, you must own a battle.net game (StarCraft, Diablo, WarCraft II, WarCraft III, Diablo II) because the only way to create an account is through the game's interface.
