I had a similar experience but I dropped out of high school.
For years the social stigma about being a high-school dropout got to me, and I was determined to enter University as an adult student and get my CS degree.
The problem was that I already had steady work as a software developer. And the entire reason I wanted to go to school in the first place was to level up those skills. It didn't help that, in my late teens / early 20s, I was working for a dot-com startup and we had coop students from the local University, and they weren't being taught anything that I didn't already know or understand.
Eventually I came to the opinion that, at least for me (not necessarily for others), formal education institutions amount to little more than institutional child abuse. For hyper-independent and high IQ students, particularly those with aspergers (I've never been diagnosed, but even my mother says it would put my childhood into perspective), class rooms are not a positive experience.
And I can't honestly look back at my time in public school and identify a single subject that I learned in class, as opposed to independently. According to my parents I was literate before entering kindergarten and I taught myself maths and history as an adult because school taught me to hate both (I don't hate either now, but the way they were taught in school divorced them from our day to day lives, created busy work and the impression that what we were being taught was irrelevant and unnecessary).
I tried online learning for a little bit in order to get my GED but I abandoned that as well because it still felt like boring busy work.
EdTech seems like it might offer the solution to younger children with my personality type. But honestly, I personally learn best by reading books, experimenting (hands on learning) and having goals that I actually care about and can relate to. If school had taught us to prepare a tax return, balance a household budget, that history gives us predictive "power" by examining how humans dealt with certain situations historically, if English class focused on effective communication rather than trying to guess at metaphors and hidden messages in the writings of dead authors who can't be asked to comment on that conjecture... maybe I wouldn't have loathed the experience so much and felt like I was just in a prison for children.
In other words, my personal experiences with EdTech has seen these trying to take a standard public school curriculum and package it in a digital "work at your own pace" format. Whereas my issue with school was at least in large part the curriculum itself. The pace was a factor too ... just not the only one by far.
