Biology E Sat 2 score?

As a freshman in high school i took the Biology E Sat 2. Today I got the scores back and got a 570. Im a little bummed about it and i am starting to stress because i want to go to a really good college. How is this score in general for this test? Should i retake it or just let it go? It was my first SAT 2 and i find it weird how i got around a 98 on the bio regents this year...please let me know what you think--i am an over achiever and this is kinda getting at me....thanks
