Yes if you want to wait to the end of the season just have your SR at 3.0 or higher and you will be promoted. You can fast track through the license by doing your 4 races or tt's in the class your in and having a 4.0 SR. So if your SR is already over 4.0 just do your 4 class d races and keep it over 4.0 and you will move up to C. It doesn't take long with the fast track system. I had my A license in both road and oval in about 2 or 3 months on being on iracing I wasn't even really trying. I know one guy that got his oval A license in 20 races lol.
WHOAH!!! all I gotta do now is four measly time trials in the skippy, and I'm automatically promoted to Class C???
Well...
