hi there, sounds like you're doing the right things... and btw, we have a little in common as I work at mclean right now, and I'm going to start at the psych NP program at yale in the fall. don't stress too much. one of the most important things (i think) is having good experiences that back up your interests. I never had a clear idea about what competitive gre scores were... Let me know if you have more questions about the application process, interviews, etc...
