I'm new enough at racing to remember all the worrying for nothing and stress that I felt as I took the steps to get into racing. So let me throw in my two cents.
I don't know if all noobs go through this or if it is just my personality type, but I worried about every step of becoming a racer starting from downloading the medical form on.
It would be ideal if there were a link somewhere on the SCCA site, preferably near the medical form and novice application form download site that would say "If you would like to be assigned a mentor to guide you through the steps click here".
Ideally, a racer from your region would contact you well ahead of your first school and guide you through such matters as the physical, novice permit application, school registration, car tech, and it would be great if they could be present during the first school.
Email exchanges prior to the school can go over things like safety gear, tow rigs, parking at the paddock, camping at the track, etc.
I'm sure this sounds like basic things to veteran racers, but these were the things that I worried about. I had a load of track days under my belt when I finally took the leap, the driving on the track was the least of my worries.
