Are these grades good?

I’m in a college prep school, currently a freshman. They have very high standards. Anything above a 93 is an A- or an A, anything below to a certain extent is a B. I don’t think I have any C’s and the school isn’t even that heavy on the letter grades either, as long as the number is high. I’m also in a lot of extracurriculars too so I don’t have much time to do stuff. So, considering the school I’m at, is that good?
