I'm applying in August also! I'm preparing for the GRE now and I will be taking Microbiology in the fall. I have a good prerequisite GPA and I'm only a little worried about my upper division GPA. After I finished my master's program I ended up with a 3.5 but I am not sure if they will also count my upper division GPA from undergrad. Anyway, good luck with the application! What concentration are you applying for? I want to do Child Health with a role specialty in Public Health.
