I'm presenting my users with a test.
When they reach the end of the test, I want to show their score in a donut chart like this (in this case, 80%):
Note that there will be other information on screen like "Hey, you passed!" (so, for example, the color will not be the only thing indicating their pass/fail status). This question is specifically about the chart.
Is a user likely to misinterpret the donut chart as an indication of their progress through the test (on question 8 out of 10) rather than an indication of their score (eight correct answers of of ten questions)?
More succinctly, is this an appropriate use of a donut chart?
