Only one of the schools still takes DAT and I'm pretty sure that is getting phased out. However, some of the best students in our class only took DAT, so it obviously isn't that big of a deal
It is no secret that many people end up in pod school as an alternative option because plan A didn't work out. As long as the applicant is strong and shows promise and a commitment to the profession, I don't think taking a different test is that big of a deal. Once first year starts, nothing anyone did before they got to school matters.
I'm sorry that you are so affected by it though
