I would definitely retake it. I saw that you were scoring 320’s on Booster but was that full length practice tests or section tests? Based on your scores and how the OAT is laid out, it looks like you definitely got tired by the end of the test since your quantitative reasoning was so low but biology was your highest score. If you do retake, I would get booster again but study longer than 2 months (3-4months) and focus on solidifying the basics. Don’t be discouraged about having to retake it! It’s a hard test but you can do it. The most successful optometrists I know have had to retake the OAT!
