I watched my 12 year old 6th grader take it. He got "masters degree". Now the thing is I watched him get 3 wrong that he should have known from recent studies (he sort of blazed through it), so yeah... I'm thinking it might be not be real 'accurate'.
The funny thing about this test is that it "guesses" your level of education, but it's all trivia. Trivia doesn't really have anything to do with higher levels of education. When someone has their Master's or PhD their extended studies was specialized. It wasn't focused on overall knowledge but knowledge very narrowly focused on a specific subject. Fun "test" nonetheless.
This is my "other" website were I hangout. If you enjoy answering these kind of questions and playing trivia this is the place. http://www.funtrivia.com/?ref=hermet
