SAT Subject Test Scores

I took Math II and Physics this past June and received and 800 on math II, 700 on physics. I’m worried about the 700. I’ve tried to look around but I haven’t found too much about what scores schools want on the subject tests. If I’m applying to the ivies and other top schools, how poorly will they view a 700 SAT II Physics on my application?

From what I read, a 750+ helps you & a 700+ doesn’t hurt.

Thanks writergirl. Forgot to say that I plan to major in engineering. Does that change anything?
