Here were my results...

Your inaccuracy by category:

Parallelogram 8.5 4.1 7.3
Midpoint 4.2 5.0 4.5
Bisect angle 9.2 3.6 0.4
Triangle center 5.6 4.0 0.5
Circle center 5.1 6.0 6.3
Right angle 1.9 2.0 4.3
Convergence 8.1 4.5 16.8
Average error: 5.33 (lower is better)

I think that put me in the 4 percentile for the test. I guess not bad.
