I got a pretty good score too (31/40, better than 81.9%). Though admittedly, while I have not studied university level social psychology I have read Dan Ariely's book Predictably Irrational [1], which covered many of the experiments presented in the quiz. It's an interesting and entertaining book, but it was a bit formulaic for my tastes, as every chapter tends to follow exactly the same structure. The experiments are presented well and are probably the best part of the book.
