Youll be fine. I was gonna say you should feel comfortable on riding on the track if youre a regular twisty rider (minus the deer, gravel, etc) but I saw you were from FL
. Regardless, youll be fine. Just remember to take it easy. Taking the Viking school is a good idea but I think youll still do ok without it. As long as a more experienced rider can show you the lines and give you some pointers.
My first time on the track was at NFMP and I went there with no track experience, although I have a lot of mileage in the twisties. I also earned my racing license at the same track and its just an awesome track to run.
As far as being on the same track with racers and other more experienced riders, I think its just hearsay. Never have I encountered an open practice run in the SAME SESSION as a school. Schools always run a separate session. NFMP usually runs advanced/racer, intermediate and novice/school. Even with an open track day, they run the school in a diff. session.
Just remember that there is NO need to push it during your first time at the track. Well, the first few sessions anyway. If you feel you can give it more juice later on in the day, go for it!
Oh if it's any consolation, Im a chick. If I can do it, you can too
I know gender doesnt really dictate riding skills but if it makes you feel better, then take that info for whatever it's worth. Just have fun
