Hi! It really depends on how good the rest of your application is. If you have a competitive GPA in your other prerequisites and your OAT is somewhat competitive you should be fine. I applied with a 3.5 GPA (3.4 science) and a 330 AA 310 TS OAT which is not the best but still fine... I had yet to complete Biochemistry, Physics 2, Microbiology, and Bio2 Lab (I put that last one off forever) and I still received interviews to all 5 schools I applied to.
It will also depend on what schools you're interested in. I got interviews to all of my schools but I didn't apply to schools like SUNY or berkeley which are harder to get into. I was interested in Nova, SCO, ICO, SCCO, and western. I canceled 2 interviews, went on three, and got accepted to all 3 schools that I interviewed at. [Nova, SCO, SCCO]
Sorry for the novel, I was just worried about the same thing when I applied so I know how you feel and I wanted to put you somewhat at ease 🙂
