I'm not sure, but I would be that there is a correlation between SAT score and MCAT. So, this is my best attempt. I would say if you have a 1100 to 1200 you could break 30. But I've know people with 1400 who end up with a 27. But you're asking about the whole population and not just a few individuals. I would say a 1400 might mean a 32 to 35. Truth is: I don't know, but that seems fair to me.
I was about to say that a 900 might equal a 24. But that's wrong because we're looking a different populations. All SAT takers don't take the MCAT, premed students, on average, probably are in the top, so we are a select group to begin with. I guess we could do a search to find out, but I'm not motivated enough to do that. Maybe someone knows.
Are you asking to see what you might end up with on the MCAT?
