If you take a class with no more information going in than the name of the subject, you're apt to be disappointed. A directed five minute conversation with the instructor prior to the class asking about background, qualifications and attitudes might save you irritation and wasted time.
I fantasize about teaching such a class myself. I can hear an eager young shooter asking me about double action revolvers, and I answer, "You should learn them . . . . seventeen or eighteen years after you've started with the single action. For a young fellow to go into them too soon would be worse than putting water in his whiskey."
Another asks, "How about 1911's?"
I answer, "Ten years after the double actions."
One more asks, "What about Glocks, Siggs, and Berettas?"
I answer, "Never heard of the first two, had a great-uncle who took a Beretta off a Japanese Officer as a war trophy. Don't know anyone who actually tried to hit anything with one of them."
Then a young lady in the back row raises her hand and says, "Sir, I think you are trying to teach attitudes that went out of fashion before any of us were born."
That's when I realize that the world may have changed without my noticing, while I was off wandering the hills and reading musty tombs, and that I don't have much that these young students need.
