JFK Jr took the bar exam 3 times before he finally passed it, so for many licensing things, I don't think it's you put in all these years then if you don't pass one test you've lost everything. Well maybe a PhD oral exam, but after so many years you WILL know your stuff, dontcha think? My nail exam, I failed the acrylic portion, you just go back and retake that one part. And besides, WE have faith in you!
