What should I do to prepare for the Warrant Officer review board?

Know your Land Nav and be sure to do your push-ups in the correct form and to standard, especially for that first APFT. Practice foot marches as well. Academics was one of the best parts for me. If you and your roommate work together, you'll have no time keeping your room squared away, as well as make your hit times formation. Strength in Knoweledge...good luck!

Learn to do all personal hygiene,make bed,secure personal items, get dressed, check your roommate, go down possibly three flights of stairs and be in formation with a good attitude in 7 minutes.

I went to my board didn't went with open mind and my self looking good.I 'm now Med Retired WO#3.
