It's not debugging as much as what us old timers call troubleshooting. At the university I had an insane advantage over those folks that had never seen a Simpson multimeter nor soldered a component nor seen a schematic. I had spent my teenage years building radios and computers followed by formal training in the military. And the Navy taught us how to troubleshoot large systems down to the component level. So college was mostly easy and extra beer money was earned fixing other students electronic devices and tutoring.
