At this point it may be too late since it is going to take you 2 or 3 months to fill out the application, get recommendations which will probably push you back to november or december at the earliest. Try to get additional course work in to boost your GPA, maybe additional upper level biology courses if you haven't taken those courses or maybe a GPA boosting post bacc. Even if you did well on your DAT the fact that is late will hurt your application. An extra year won't kill you. AT least your GPA is above a 3.0👍
As a guideline try to get all the applications to the schools by august/september, meaning processed by AADSAS and mailed to the schools by then. A lot of schools tend to fill up by january/february so a lot of spots are taken from the initial batch of applicants that they get. Submit to AADSAS by mid/late june. Aim for these artificial deadlines for the next cycle and you will be all set.
