"Clue #8 says that one of those two (either Art or Pre-Calc) is in room #114, and the other is Avery (who you already know isn't room #129). So any way you slice it, Art is either in room #114 or in Avery's room (which definitely isn't 129)."

I finally got it when I started thinking of it as : Avery is not #129, AND #114 is not #129... (so BOTH art AND pre-calc can't be #129...
