In the real DAT do you encounter questions for cube counting that ask for ZERO sides painted? I see people write the tally method from 0-5, but some right it from 1-5.
Not sure about the real DAT, but I've had that happen on practice tests (I think bootcamp?) It's also useful if you have extra time remaining on the PAT: if you count all your tallies and they equal the total number of cubes you see, chances are you got it right 🙂
