Congrats
I can't really offer any advice for the DAS as i passed mine so long ago {17 yrs} that i really don't remember it too well {well, i remember the test but any tips i may have used} also it has changed a lot since i did it.
I guess the likes of Stu 2K7 {and others} who passed recently are the ones to help here.
All the best for test day.
