Can anyone give a reasonable explanation why Tom Henry's exam prep materials would ask questions like "What would you use to sharpen an electrician's knife?" or "Should you use a hardened steel hammer on hardened steel?" It's bad enough having to go through this BS all over again 16 yrs later because I moved out of originating licensing state. I don't know anyone who has time to waste with materials like this. I figured I would get a different perspective from other than Mike's materials- seems to be a big mistake.
