Hey Ian,
Thanks for reaching out!
Yes, this is possible. What you would have to do is make the events for the “attending sessions” and such, and then on the first event, add tickets for the whole course.
Do not add any tickets for the rest of the courses.
You unfortunately cannot sell tickets with Events Calendar Pro’s recurring-events feature, by which I mean you cannot have these events all exist as one “series” together and sell tickets for them all in unison.
But you can have tickets on the first event, which will create an Attendees List which you, as the event organizer, can then check against for the rest of the “attending sessions” and such.
Let me know if this information helps!
Cheers,
George
