@lookingforward is on target, as usual. Last year our HS had a bumper crop of exceptional kids getting into tippy top colleges. Not that it was a total shock, but it was a bit surprising that Harvard guy did in fact get into Harvard, ED. He was a strong student, but NOTHING like the OP. Probably did five APs, and our school offers close to twenty. He was nowhere close to being Val, did not score super high on his ACT or SAT. He was clearly bright enough though. White guy from a major city suburb. (Sorry to speak in past tense, it’s easier for the purpose of this narrative. He’s alive and well, at Harvard.)
So what did the trick? No idea what his essays were like. Probably good, but I know for a fact his family didn’t hire private consultants or anything. He was no doubt close to an english teacher who critiqued his essay. It had to be his ECs and his teacher recs. This student was universally well-liked. I am certain he had truly outstanding recommendations. He was elected student body pres two years running. He was actively involved and actually made stuff happen at school. He was like this in middle school too. His big passion was politics and government, and he spent a lot of time going to special events at the state Capitol. As far as I am aware, he didn’t do a sport, because he was too busy doing other things. He was definitely involved in community activities, and he attended school board meetings, which were super boring and dragged on for hours. (I have attended a few myself, and it was always clear that when the board addressed him, they knew him well.)
I am pretty sure he knew Harvard inside and out before he ever applied. Maybe he read up on the “spike” theory, who knows. It’s the special sauce that’s important. He offered them a deluxe burger with special sauce, and they liked it. Find your special sauce.
