I NEVER said it was mandatory, nor did I say every instructor will teach you anything. I also, on my way to becoming an instructor have taken courses from instructor's that I'd put to shame one on one, but they have the means to get me the card that allows me to "ADVANCE" Did I learn aqnything more than what I could have learned on my own??? I think not!! I think it is our duty to interview the instructor that you are having train you, and ask exactly what you will be getting for your money. Yes, it is true that SOME instructor's are in it only for the money, while other's are there for their student's! It is up to you as the student to determine which kind of instructor YOU will be giving YOUR money to. Also, some student's will take away different knowledge from the same class. You need to find an instructor that works for you. Before I put any money down on my technical training, I interviewed three different instructor's until I found the one I felt comfortable would teach me what I wanted/needed to know. Heck, the one I went with even allowed me to sit in on a classroom session, to check out his style. You wouldn't go out and buy a car without checking it out, or even giving it a test drive would you? Also, if I wanted to learn to drive racecar's I wouldn't go to Sears driving school, I'd go to Richard Petty's school of driving or someplace like that. It is YOUR duty to do a little research on the instructor/class that you will be enrolling in, so that you will come away with what you wanted to come away with. MY $.02
