I agree with the other replies. Except that I don't know why you want to go to a masters program in the first place, and for what degree. MSW? A psychology MA? Either way, you've got to have that GRE taken and score well.
I do disagree with the others though in that I believe recs from your class professors, who are really only vouching for your classwork, can be perfectly fine for a general psych masters programs. A competitive MSW program is a different story. The thing is with these psych masters degrees is they have no funding, and they're pretty useless in that in most states you can't do anything with just a psych masters -- you need some kind of doctorate, msw, mph, mhc to do anything interesting. so they're really just looking for students who can come in and pay tuition, the money from which they use to fund students in their doctorate programs. so don't be discouraged.
also, get in touch directly with the heads of the departments at schools that interest you. try and meet with them face-to-face. they very well may still be accepting for fall, but talk to the people in the department who it's hoped know more than admissions. even if they say "no" now, you never know -- someone who they accepted may decide to go elsewhere, and by the fact you made the effort to go to their office, they're gonna remember your face better than someone's name on a paper application, and may feel your efforts demonstrate such a strong interest and commitment that you're being later with the application can be waived, assuming you meet their admissions requirements otherwise, eg for grades etc.
if nothing else, many masters programs accept for spring, with deadlines in the fall, giving you plenty of time to study and get a great GRE score.
Good luck!
