It was mainly because I said I wanted to learn a trade rather than get a loan for college and since I was a C student and barely passing I think they just realized they couldn't make any money off me.
Not everyone needs to be an "academic". I've learned far more through my own pursuit in interests than any school could have taught me.
I had good teachers and bad ones. My English teacher passed me only because I wrote him nonsense essays he liked. Because I couldn't sit down and read a book in a week.
In the end. Cognitive ability isn't as simple as a GPA or "normative".
Keep raising another free thinker. We need more of them. 🫂
