    Need help with the Professor Portal achievement.

    Hello!
    I've recently decided that it would be fun to s-rank Portal 2. I wasn't wrong. I've had a blast getting them all but now I'm on the last stretch. I've got 2 achievements left, one of them I have a partner for and we can do it tomorrow, it's just a bit late now. The other is a bit harder.

    I need a partner who hasn't played the co-op before and is willing to do the calibration course with me. I'm on PC so the partner has to be on the PS3 or PC.

    Thanks GB!
