Has anyone emailed schools that you sent your app into to just preface/warn that you're retaking the DAT so they don't throw your app into the no pile right away?
You might send it before your secondary. Maybe something along the lines of: you are scheduled to take the DAT on (date), and have studied hard so you expect improved results (if this is the case). So if possible, I ask that you consider my DAT retake results before making a final decision on my application, aadsas #. Thank you, your name.
