This test is surprisingly tough. I disagree with the way that a few of the questions are phrased, but it's a fun test of your classical physics expertise.
I am a physics graduate student, and I took this test and got a 72%. I did not like some of the questions where they asked about force, but everything was in units of kg. That did not make sense to me. Otherwise, I thought it wasnt too bad a test. Reminded me of some detail stuff you forget when you're on your 4th semester of quantum mechanics and you don't really think about the simple stuff much! :)
