not true, say you are applying for a job where you use power tools and table saws and stuff, you can put down that you took shop class and have experience using tools or if you apply to work at a mechanic shop and you have in the past helped people do an oil change or rotate tires you can write that down or if you took a car class in school. anything helps,
just think if two people applied for a wood working job that only has one open spot and one has no resume and the other has a resume but it only says I took woodshop in high school so I know how to use power and hand tools very well along with the safety precautions that come with it. who do you think will be called back.
