Good talk, everyone, good talk. Thanks for your help and quick responses!
I think I've narrowed down a few schools that have relatively few prereqs, seem fairly open to non-backgrounders, and have programs and professors that fit my interests: McGill, University of British Columbia, Ohio State, Gallaudet, and Northwestern.
For a few of those, I would only need between 1-3 prereq classes before next Fall...so I'll plan on taking those classes ASAP, shadowing a couple SLPs, communicating with those schools, and applying this year. We'll see what happens! I definitely cannot justify taking out another full year of loans just to take a handful undergrad-level classes at an expensive, uppity private school (sorry, NU), but if I don't get in this year I will re-up and finish prereqs online somewhere (perhaps USU, thanks for the tip!) over the next 2 years and try again!
I honestly feel a little silly with how much of a whirlwind decision this is; I realize it's probably not the most practical or normal way to go about things, but I feel like I just got lit on fire. The more I read about everyone's experiences in school, and research in the field in general, the more excited I get. It's cool stuff!
Question, though: why are there seriously NO DUDES in this business at all? I was looking at current students profiles at a few different universities, and there are no Y chromosomes to be found anywhere. I know all applications *should* be based on merit and not quota-material, but...is there any chance that being a guy will help/hurt my case?
