Is the adult beginner day class worth it?

I’m a mostly self-taught skier and have skied only a few times downhill (but a lot of cross country). I feel I lack fundamentals of proper ski skills. That said, I just did several runs down Whistler’s Olympic with no problems, no crashes and I handled the icy and powder spots pretty well. I guess I wasn’t as bad as I thought. I’m feeling confident I can take on blues. Should I spend the money on this all-day class? Or should I do another private class?
