Also I practice dental hygiene and I get a chance to closely assess people's health through their teeth and gums. It's amazing what you can deduce from these things after years of practice.
It took 6 months to study, and I got a low score, about midway between passing and 80%. I used the 6 months to really read the manual and answer the questions in the study guide (workbook) but frankly I didn't do them all.
The test did not seem difficult. I was one of the first ones finished, but I'm always that way. I didn't doubt any of my answers but obviously I got several wrong.
It's funny how I am at taking tests, yet some people "lock up" in a test situation. I was always terrible at ball sports, though. I was always afraid of the ball- either it was gonna hit me and knock my teeth out, or I would miss it and embarrass myself, either option was gonna be bad, and that was why I was afraid of the ball. Never afraid to take a test though.
Anyway I hope this helps. --Connie
