Sal. I have been instructing for almost 10 years so I can give you a couple of easy to remember tips right here.
1. Learn where the flag stations are and learn what the flags mean. You will be shown this at the very first drivers meeting you attend.
2. When you are driving the correct line around the track(you will be shown that the very first day) NEVER get out of line to let somebody pass you. The track belongs to the person running in front.It is up to the passer to find a way around you.(the fast guys know how to do this)
3. Do not attempt to impress your instructor(because you can't).Do not try to scare your instructor.(he already is)
Good luck,
RD
