I am not certain why, but I had a difficult time mentally rotating the last three (#8, #9, #10). The first seven (#1, #2, #3, #4, #5, #6, #7) seemed much, much easier. At some point, I got tired and just guessed, without really knowing (my answers for the first seven were not guesses).
I got 9/10 and also found the last three harder. I messed up the last one despite finding the one that was impossible because I then went on to check the others and when I went back, selected the wrong on of the two that had the diagonal black/white division on the top face.
I think the test was designed to be progressively more difficult. The errors in the beginning were easy to spot, like squares that had to be on opposite faces appearing as adjacent, but the ones at the end were more subtle, like patterns that were on adjacent faces but would be rotated 90 degrees on the face to match the 3d representation.
