Is it possible to get in if your SAT is below 2300?

86 non-residential undergraduate students total.
21 received institutional aid.
Does this 21 include all 4 years of undergraduates?
Seriously? @NickFlynn gave you the link.
If you are desperate for that knowledge, look it up. You shouldn’t expect others to do your research, so Caltech wouldn’t fit you.
