Scoring problem with Circles?
I don't think that Circles is scoring correctly -- many students who said they had problems and didn't get it right ended up with an A+.

Circles uses a timer that could be affected negatively if the CPU on the computer it's being played on has a high load. So if a lot of applications are open or an application is CPU intensive, it's possible the timer will become inaccurate and cause inconsistencies in the scoring. We would recommend trying to close all of the other applications open on the computer or restarting the computer that's having this problem and see if that helps.
