I had planned to race at Fuji, done hours of racing simulations and all, but I came down with a headache

I tried to drive a gr. 3 car but I was useless.
I am fine now and my practice consistency in a gr.3 car is paying off. Doing very well in the new daily B race.
I am new to this, how often do the daily races change?
I think I might give the next nations cup gr.2 race a miss, even if it is Spa that I know well. I can peddle a gr.3 car well but gr.2 cars are a bit out of my grasp.
Looking forward to the gr.4 manufacturers cup race though. I have learnt that circuit well with it being last weeks daily B race
