Numbers are important, but they are not everything! My GRE is a 149V, 145Q and 4AW. I took it four times. My overall GPA is a 3.5, but I was determined to be more than just a number!
My junior year I joined and became very active in NSSLHA, got involved with research, started working two relevant jobs, observed as much as I could (over 60 hours), completed over 400 volunteer hours, completed 50 clinical clock hours, and tried to do everything that I could to make connections with faculty and have a killer resume.
Even with my average GRE and GPA numbers, my other numbers (clock hours, volunteer hours, and observation hours) helped me to stand out because I wrote about them in my personal statement. I have now been accepted to two great schools!
You have plenty of time to make those connections and beef up your resume, but those things are not going to do themselves. You will have to make all of it happen, but it will pay off! Do not wait for opportunities to come your way, CREATE them!
