Please don't advertise in the comments, but getting into arguments over ads is not constructive either. Draw a circle while staying as close to the template as possible. When you're done, release your mouse. It will show a graph of the distance from the actual circle over the time you drew it. (lower is better) If it says "Not a circle", you made the circle too quickly or you didn't close it all the way. My best score is 3.06!
