From my experience, you can send your kids as long as they have a piece of your ID or credit card used to purchase. If this still doesn't work for you, I would contact a blue jays sales rep and complain. You might be able to get a refund.
Haha this is kind of true. In my school, the tutorial is worth around 10% of the final mark. And people still never show up.
I would love to answer any other questions you have about the school system. Ask away!
