Applying to Optometry for Fall 2016

Hello!

I will be applying for optometry school this summer for Fall class 2016. I have a 3.53 GPA but have yet to take my OAT. I am currently in the Kaplan course and set to take the test at the end of June. I would like to make myself more competitive then just scores on a paper. What else can I do to really solidify my chances! I will be applying to Midwestern, MCPHS, Southern, Southern California and Pacific. Any tips would be great!

Thanks!
