I'm a foreign exchange student and I got 630 on my two SAT Subject Tests in Physics and Math 2. Is that good?

Question

I studied one year in the US.

Answer 1

"Good" is relative here.  The average American and the majority of American high school students score much below you.  However, if you were expecting to go the very very best universities in the US like Harvard, Stanford, Yale, etc. these scores are very mediocre.

Answer 2

thats pretty good for physics especially because so many people say that the physics subject test is very difficult. I think you should increase your math 2 score a litle bit more...

they seem to be good scores!
