Yes there are. I suggest that a) check YouTube, and b) you walk in to Apple Storr and ask at a quiet period (check Google to find quiet time). Apple agents love to talk, help, share, compare.

In the apple store are people who can help you to figure it out how apple watch works. They answered all questions about watch and they walked you through their devices. Good luck.
I know they have classes for sure, not sure about Apple watches. You need to make appointment with them
