Just went to MEPS and took the Depth Perception test and passed A through E. I believe A through D is required. It is very challenging but my biggest piece of advice would be to take your time. Don't let the workers at MEPS push you into hurrying that test. Really focus and TRUST YOURSELF. I also would advise hydrating and getting a good night sleep the night before if it is something that you are concerned about. Good luck.
