OP, your scores are fine. Good luck applying this summer.
To everyone else preparing for the upcoming cycle, STOP READING POSTS ABOUT SCORES! I've browsed this forum since 2009 and applied/got accepted to opt school for the Class of 2015. I took my OAT the summer after my soph year and made a 320. After reading on the forum about how everyone else was getting ~340-360s with similar GPAs to mine, I was discouraged and decided to take the test again after junior yr and right before the OptomCas opened. I ended up with the same score. My gpa was 3.71. When I told opt schools I had retaken the test, they all laughed and questioned why. Almost verbatim from one school, "We commend your choice to retake the OAT, although unnecessary. Your original score is very competitive for the upcoming cycle. I look forward to seeing your new results, and be on the lookout for a interview invite from our school."
Short story, I wasted an entire summer of studying and stressing over a test because other members on this forum said I needed to to become competitive. Not at all bragging, I applied to 5 schools; interviewed and accepted at 2 and declined interviews at the other 3. So, PLEASE stop comparing yourself to everyone else on here! Most people that post their scores are either 1) scared because of previous posts, or 2) arrogant kids trying to boast about their accomplishments. My score wasn't anything spectacular, but I will be an optometrist come May 2015. 😀
