Sorry, off subject again.....Plates are a pain in the butt. I had one civilian AME who only required a portion of the plates to pass. Current exam office requires every plate (book looks bigger every time I go in!) One office never made me do them again after I passed the first time. Bottom line, there are always a few that are tougher than others to get for my 50 year old eye balls. I miss the old Navy FALANT - it was easy.....red, white, green. At least we don't have to do the old depth perception circle test in the civilian world!
