FRC has a fairly large number of classes for the cars we race. Its not possible to race all these classes at a single event, so we group certain classes together to be raced at each event.

We basically start at the top (Group A) and go down the list for each subsequent event, cycling back to the top after we've gone through all the classes.
Here are the 2020 class groupings:
