Hi! I have not been accepted still in the interview process. But I have spoken to people who have been accepted w/ low GPA/OAT score. Ideally, if you have a low GPA then of course you would want a higher OAT score to balance it out however schools also look at your extracurriculars/LORs/experience as a whole so it is possible to be accepted with lower scores.
The schools that I have heard that accepted students like this are MCPHS, KYCO, and PCO. Some schools accept conditionally meaning that they will accept you if you retake your OAT and score whatever score they are wanting (typically <300).
Hope this helped!
