You know I guess the teacher isn't a bad guy he is just not the greatest teacher in the world. I take back all that I said about this guy. From now on I will just have to teach myself from the book. I do like what the guys at TUTORINGZONE.com do as well. Maybe you could try their site. He went into chapter 22. He also announced that the next mini exam will cover 3 chapters instead of just 2. The next mini exam will cover chapters 21, 22, and 23. Today he talked about these things called phasors and I could not stop thinking about Star Trek.
