It took me the entire 4 hours given to complete my test(25 questions total, most like those 4), in which I made about a dozen revisions and finished feeling only slightly less confused than I was when I started. Uschi answers 4 questions in 4 minutes, and gets 3 out of 4 right. The last one was Ectothermy, not Endothermy.
You shame me, Uschi.
I did get a 90, though.
