3: All present but errors in spatial arrangement

2: Numbers missing or added but no gross distortions of remaining numbers

1: Missing or added numbers and gross spatial distortions

0: Absence or poor representation of numbers

Presence and placement of the hands (maximum: 4 points)

4: Hands are in correct position and the size difference is respected

3: Slight errors in the placement of the hands or no representation of size difference between the hands

2: Major errors in the placement of the hands (significantly out of course including 10 to 11)
