If you used to believe in God, and have about 30 minutes to spare, you might want to take this survey by the Atheist Research Collaborative:
“The study is open to those who are at least 18 years of age, and those who once believed in god(s) but do not now; this means you are not eligible to participate if you have always been an atheist/nonbeliever. The survey is a maximum of 76 questions, and a minimum of 64 questions. On average, the survey should take 20 to 30 minutes to complete, although individuals may find that it takes them more or less time than this, depending on their answers. The survey can be found here.”

it’s not hard, but remember to keep an eye out for the trick questions.
