I agree, two questions are about where you're living (northern or southern hemisphere and you latitude) and I don't see in what your location in the world has to do with the fact that you're depressive or not

That's actually a legitimate question in regards to seasonal depression.
The reason these quizzes should not be taken seriously is that they are way, way too overt, and can easily be cheated. A true, genuine psych evaluation test cannot be cheated. The funny thing is that someone who was not depressed before can take this test, have the test tell them they're seriously depressed, and then the person believes it and becomes seriously depressed. (I've had one and a half years of psych so far, in my third now)
