Hello,
Recurring Events and Tickets are not supported and by that we mean if you create a recurring event with a ticket all the tickets are considered part of the first event in the series and not each individual event.
So that could work for you as you could create the ticket with the recurring series and set the end sale date for the first day of the class and the tickets would not be available anymore for the remainder of the class.
Or you could create the recurring series and then edit the first event and add tickets to just it.
Cheers
