I am going to be a sophomore next year. My graduation year is 2023. I went to check out some colleges, and I found people who got accepted to Harvard for the class of 2023. Am I supposed to submit my college applications now or wait till I'm a senior? How come people from my graduation year already got accepted into colleges?

Well, people in your graduation year didn;t get into collages, because well. It's technically impossible unless they are a prodigy or they are signing up for a class in collage. Wait till your a Junior or Senior. Believe be, Im a sophmore.
