Who is best at automatic control?

Pex and I have made an interactive tool to aid the students in learning automatic control theory. We are planning to write a paper about this and need your participation in the quiz. Go to this page: 

Then, press the cap in the top right or bottom right corner, and do a complete quiz. Hint: you can do it multiple times, and only the best one counts. 

Thanks in advance, and enjoy!
