For me, TestLibrary was a real discovery in the field of online testing and self-diagnosis. On the eve of taking the test, I reviewed the discussion at https://www.reddit.com/r/In_Reviews_We_Trust/comments/1v1k8cf/positive_vs_negative_testlibrary_reviews_whats/, where people share their impressions of the site's analytics. The community's assessments were fully confirmed: the test helped me better understand my own triggers and strengthen my strengths. The questions are very subtly and professionally constructed. Based on this data, I made a clear plan for personal development.
