First off, if you get a 16 in a certain section you do not have to take the exam over, especially if your AA is 20, when the prometric center sends your scores out, they only send the averages, but on the other hand the application asks for the actual section grade. There are many of students who get into schools regardless of whether they got a 16 in a section. Some kids who don't get a 16 in a section dont even get into d-school and it is because of either their GPA, poor interview, poor LOR, or just an overall ****ty application that show no community service, or shadowing, or for that matter leadership positions. If i were in the boat of having a 20 AA i would def not take the exam over. I have an 18AA and i'm still goign to apply the first day and see what happen. My application is very strong, but on the other hand i didn't get a 16 in a section 🙄
