I think it's all really dependent on the school and how strong the average applicant is. The general baseline score for the TEAS for the three schools I applied to were 65%, but my top choice said the average accepted student gets a 95%, while the others were way less rigorous. I ended up scoring a 92% and got accepted to my second pick. I'd strongly recommend reaching out to your advisor and see if they have any information on the average accepted student score versus the minimum requirement. It should help give you better insight into whether or not you should retake the test. Best of luck!
