Are you saying you have a week and a half until your DAT?
If you've already studied the subjects and just practicing, I would say one a day is slightly overkill, do one every other day and review in between. Or take a break tbh. For the week going up, I did one practice exam a day but took the weekend off to just relax and review a bit. I will say do one a day maybe like starting 3 days before the exam .
