6th overall out of 42 teams is nothing to sneeze at. At States, you have quite a few schools that have been doing SciOly for ages and have most of the events down to a science (literally
It takes some hard work, but it's far from impossible to steadily improve your placements at State, until eventually you find yourself in 1st or 2nd. Talking from personal experience, Lake Nona High School improved from 21st (or somewhere in the 20s, I don't remember exactly) in 2016, to 9th last year, to 7th this year. And of course, River City Science Academy went from 6th last year to 1st this year, so Archimedean, Orlando Science and co. aren't untouchable.
Now that you've been to States (good job making it to States your first year, by the way), you have a better idea of what you're up against, so you'll be ready to really bring it next time.
