I was the weird kid. As an undiagnosed autistic with ADHD and an aptitude for the exact kind of easy material in high school, I broke the grade curve wherever I went.

Teachers changed decades long rules to curve the grades off of the second highest score instead of the highest. Teachers who never remember a name knew who I was.

10th grade, unofficial start of high school in my state, I was at a brand new self paced high school where we all got chrome books. We did online classes in the school building, and at home if we wanted. I would do a month's worth of work in a day, then I'd do nothing for the next week. I finished my entire health class in three days. Some teachers hated it, but they gave up trying to change my behavior by the second semester. I did 2.5 years of high school in a semester and started college. I was a sophomore in college before I was 16. A few other students followed behind me and started college early too, but I specifically ran the system so hard that they throttled the program right after I left so it was a lot harder to speed ahead.

I started a year long AP biology course in its second semester because it was full at the beginning of the year. Starting a semester behind, I got 137% in the class and a 4/5 on the AP test. I was also one of two students who got a 5/5 on the AP psychology test. I finished my college chemistry class before the professor got halfway through the course material.

Word of these accomplishments got around at any school I attended.

I don't mean to brag, I'm just answering the question honestly and to the best of my ability.

TL;DR I was the weird kid because I broke the grade curve wherever I went and ended up a sophomore in college at 15.
