Portal 2 Professor Portal Achievement help?
The achievement requires you to complete calibration course with a friend online who hasn't played before. I tried finding a person online and adding them to my friends while the game was loading, but after the course i got no achievement. Can anyone help me get this? My GT is Hydra94

You have to play a player that has never played portal 1 or two ever. They don't have any achievements or have even started the game. You also can't die.
