While I did take an electronics class in high school (30 years ago), I did not get much from the class as they had a TRS-80 model 1, once I saw that, it's all I messed with. The teacher was very laid back (Vietnam vet) that did not run a very strict class. So I did not retain much. I have been doing minor repairs to monitors, AC Adapters, and anything else with bad capacitors. Every once in a while I try something a little more involved than I am used to.
