High School and they actually promoted me, I didn't earn it. At least not after the 9th grade, when they screwed up the Educational System, the last 2 weeks of School in 1970. I learned nothing from that point, I might as well not been there. They passed everybody, I suppose they didn't want to admit there New System wasn't working. But then again, they new what they was doing, and eventually everyone accepts it today.
Of course I have had to do some training courses for work over the years, mostly mandatory politically correct crap, like Diversity.
