It does seem like alot of common sense stuff. Dress like your going to be in public (I think we've kinda lost the meaning of that in our generation). Dress like your going to be in class, not cleaning out horse stalls (if you can help it, some schedules may not allow for that). To me that doesn't mean dress up, but be presentable. Make people think well of you. I think it's also important to dress comfortable, so you can concentrate on your class.
Do your homework... that a new one! Our instructor has us do the work before we come in, then he talks about it and/or we do skills. If you don't do your homework, you don't really have a clue what's going on when you get to class.
I go online alot and surf for info on everything. What you find is not always correct, but if you know more, you can ask more intelligent questions.
Absolutley show respect!
My instructor is a stickler for doing things the best you can. I think that's great! He wants you to actually put your junk away when your done with it. He talks about taking care of the little things. Taking care of your equipment. I'd rather practice and test with him than anyone else I've met, b/c he's not lazy, and will make sure your doing things right. Anyway....
