Free/Low Cost Classes?

Just wanted to see if anyone knows about any classes that are free/low cost. The typical ones that get recommended are the Stop the Bleed/CPR classes that are provided by the community (thank the volunteers!) Also will be looking into taking a WFA/WFR class when I can afford it.

However, I recently read a comment that recommended Hunter Classes that are provided by the state - low cost and filled with information! I just signed up to one recently. Got me thinking; does anyone know anything similar to this? It doesn't have to be stuck into one category... any classes that you know and want to pass knowledge on about? I don't got a lot of money myself and I'm sure there's others in the same situation. Thanks!
