Thanks for your email.
In answer to your question above. Imitate your teacher/instructor as closely as possible. Do your best to do what they ask you to do. RELAX, "Don't worry...nuthin's gonna be alright!"
Enjoy these discussion groups, but don't talk so much. Don't try to get it perfect by discussing technical things on the web. You'll get so many viewpoints (some from "yonkyu-shihan" web addicts who think that because they are free to have an opinion and express it.. that it means it's a good opinion)
Sorry for the small rant!
Save the technical questions for your teacher.
