10th grade is when I had physical science, so must’ve been 10th grade.
I still have a 10 pg report I did on Black Holes that year later on. It was JUST BEFORE Stephen Hawking came out with “A Brief History of Time”, so I don’t think any of his stuff showed up in it. I should type it up. Last time I checked, even though I wrote it in 1987/88, it still holds up I think
So yeah, I was 15/16 most likely.
