Thanks for your insight. It's good to know which classes are considered more difficult so I can prepare myself. Classes once per week is so much more doable than two or three days per week (electricians). It's tough having night school more than once per week when you have young kids. I feel really bad leaving my wife by herself with the little terrorists, because I've done it when she is out-of-town for work, and it'll make you crazy sometimes. lol
