You need to practice your oral board answers until they become second nature to you with a handheld voice recorder that goes everywhere your car keys go. Hearing your answers will help you get your timing, inflection, and volume, and also let you know where to cut out material, get rid of the “uhs” and other pause fillers, or to find out if you really sound like Donald Duck.
You need to get married to your handheld voice recorder so you can listen to what the oral board is going to hear out of your mouth. This little device will narrow the distance between you and the badge you’re looking for!
