Are you an Indigo?
There are several Indigo tests / quizzes on the internet, but this one seems to be the best, in my opinion. After answering the last question, just be sure to uncheck a box about wanting further info (I can't remember what it says), or it will take you on a detour that asks you to sign up for something instead of just giving you your results.
Are You An Indigo Child Test - by lonerwolf
I scored 78 out of 100. I'm way past my childhood years, so I had to answer several questions by remembering how I would have answered them in my childhood and early adulthood. The rest either fit me at all ages or never fit me at all. I first discovered the Indigo concept last year and, by my estimates at that time, I fit about 75 percent of the characteristics; therefore, this test was further confirmation for me that I really must be one.
