When you complete the designation you don't have to attach a document showing all of your exam results. If I can spend 30-40 hours studying and pass, and I can have a life at the same time by going out and spending time with friends and family, Why would I ever waste a year of my life studying "300-500 hours"? I've never understood this type of person. Big picture, study enough so you can pass and then enjoy your youth while we still have it.
