text: It's amazing what Youtube offers these days. To include tuning a mass spectrometer. I looked. 
  
  As to the UA system. It's a disjointed and pretty much 3 seperate entities. Some courses taken at one university are not recognized or honored by the other two. It is the UA system or is it not? Or is this just another way of scamming a student out of money for courses that won't be honored by the other UA campuses should they decide to transfer?
