It was a beginner course... Not that I'm complaining, as that was perfect for me. It was 2 hours, they went over how to hold a chef's knife, how to hold your fingers out of the path of the blade, and went through basic techniques for how to dice various vegetables. About 20 minutes was spent talking about what various knives are used for and how to care for them.
If you already have a strong foundation and know that your foundation is doing things properly, it might not be worth it. But if a refresher on the basics sounds good, it should deliver on that.
Thanks.
