Yeah I failed mine too 14 years ago or so. The tech said it was the highest failed item on the test. I don’t recall what the retest involved but I can tell you it was SUPER easy. I have never had depth perception issues. Once I found out it was always 2, 3 or 4 and never 1 or 5, it made life a lot easier and I never failed again.
