One daughter was invited to take the SAT as a freshman in high school. She did well, but definitely way below 1480. She is currently studying for a DVM at a university with a very good program.
One thing that comes to mind is that if you are a strong enough student to get a 1480 as a high school freshman, then depending upon where you are there might or might not be a lot of other students who are “like you” in your high school. Depending upon how this is going you might want to see if there is a Mensa chapter for high school students in your area. Also, you should know that when you get to university you will meet a lot more students who are “like you” in ways that matter, such as your interest in education and learning and doing well.
