I sure disagree with "tbmpilot" about "don't speak unless spoken to. Yes, do wear a tie -- it's kind of a tie-wearing company. BUT -- if you've got a question in class, ASK IT!
May not seem like it, but the instructors are (a) interested in trainees' input, and (b) are getting paid to make sure the trainees understand the stuff they're trying to shovel into them. If you don't get it, they aren't succeeding. If you listen to the instructors chat in the office, you'll find they aren't impressed by trainees who sit there like inflatable dolls.
Intelligent questions or comments are welcome. Often those questions are the same ones adherents to the "don't speak" philosophy would like to assk themselves, but don't. Be sure yours doesn't reveal that you've been asleep for the past hour. . . .
