All you have to do is lie...................trust me on this.
Go to a track day sponsered by Team ProMotion and tell them you've done a track day or two with NESBA. They have no way of confirming this. They will put you in the Beginner (White) group but you won't have to take the silly intro course that they "make" you take if you've never done a track day before.
That's what I did some years back.........................
