Competition between internationals

Hey guys, I have asked this question on another forum, but I will ask it here too. I am an international student applying to the astrophysics program in SSP (Summer Science Program) and my friend is applying to SSP too but to biochemistry program. The problem is that I and my friend are from the same country (and the same school…). Do you think if there is going to be a competition between me and him if we are applying to different “sub-programs”? I am not trying to be hypocritical, but his SAT scores are well higher than mine and I am pretty much concerned about it.
