OAT and DAT question.

Hey guys, I was thinking about taking the DATs since its, so closely related to the OATs. Since both test were made from the same people and when I signed up for the OATs it asked me if I had taken the DATs within the past 3 months. I was wondering if anyone here knows if they allow you to take both tests within weeks of each other. I know they are two different tests, so I would think you can. I know you can't take the OATs again for another 90 days, so I'm wondering if you can take DATs within those 90 days. Anyone done this?
