A Thorough Enneagram Test
You can download it here (it's an Excel document):
Enneagram Test v.5
Remember, this is quite a long test - it will probably take about an hour to complete. The good part is, you can save it and continue it whenever you have time. The results can be verified as you take the test (they're computed on the 2nd sheet of the document).
Hope you enjoy it, and leave a comment with your opinion if you like.
