We all must remember that the NEC requirements are the minimum for safety. Your test will be to see if you understand that minimum. What you do in the field should always be better than the minimum. I had an instructor say in a class one time that he didn't want to put a bunch of minimum rated electricians out there in the market place. Simply passing the test wasn't good enough. I'm sure you know to study hard and do the best you can on the test, and in your endeavor as an electrician. Wishing you the very best.
