Usually for most clubs, they came with some sort of class room sessions for level-1 or novice group or whatever different clubs calls it.
Also just wanted to point out that NYST’s PTR school and Members Trackday thing only have 2 groups, depends on track density, I can see how it can be a problem. The speed differential between new intermediate and expert riders on big bikes can be too much to a point that it can be unsafe. Besides everyone will try to get to the Int/Adv group in a hurry so they are not being seen as “Novice” will ended up packing the Itm/Adv group with too much traffic.
There is a reason why most if not all clubs run 3 groups minimum. I was kind of surprised when I learn about that from NYST’s trackday info…
