Figure 1.

Hypothetical exam sheet with grading (green rectangle for correct, yellow circle for incorrect). Xs on bottom of attempt 1 indicate that these samples were not present on their first attempt. Zidane was an early high scorer. They got everything correct on the first attempt and missed only two on the second attempt. On the final two attempts, they only had to identify samples yet to be correctly identified twice to complete the assignment. Tidus started poorly, but with the flexibility of this format was able to make up for a slow start and still do well on the exam as opposed to being punished for early struggles.
