How much “smaller” are the schools you’re looking at - or which?
Obviously what works best for you is what you need to do and good luck. Just remember, you can make a big school small but not vice versa.
But some kids definitely excel at different size schools.
I do think you can get to know your profs anywhere - but it takes effort - like regular office hours, etc.
Anyway, whatever best works for you - good luck.
btw - editing to add this thread - i just read the first two messages (no longer) but it might give you some insights into your thoughts.
