I'm not sure what Middle School is, I live in England :p
Well, here college is a HUGE step-up from high school. Like the hardest stuff you learn in high school is like the most basic thing you have to know in college. But there's so much more freedom to do whatever you want and I can finally get a job now, which is great and stuff. But seriously though I'm like getting behind on stuff now because college is something else compared to high school.
