Don't be afraid to ask questions, no matter how stupid they may sound. Chances are there are others in your class that want to know too and are too afraid to ask. One day we were in the kitchen and our instructor realized we were out of butter, he grabbed two quarts of heavy cream thrust it into the hands of the nearest student and said "get me some butter" and then proceeded with the cooking demo. It took the instructor a few minutes to realize the student had stood there horrified with the cream. He asked "What's wrong?" the student asked "How do I make butter with this?"
The instructor then realized the student had no clue you could make butter from heavy cream. The instructor then asked who else did not know you could make butter from cream? Four other people raised their hands. He looked shocked at first but then smiled and proceeded to demonstrate how butter was made from cream. So don't be afraid, be fearless and use and abuse your instructors for information. You paid for them, use their knowledge and experience. Don't be afriad to challenge them either. My instructor liked that.
