This might not be the answer you are looking for, but the focus should be scoring high as possible on the DAT without worry of missing a cutoff, too many students rush to take the DAT when not fully prepared and many times it leads to a retake, which means waiting 90 days, plus the added expense and anxiety. Taking the DAT when you are fully prepared allows you put the DAT behind you and worse case is you miss a cycle, but you still meet the objective of becoming a dentist. A year off isn't so bad, you can relax, work and save some money, those are things that won't be so easy to do once you are in dental school.
