Although I don't know much about being a CPer, I do have experience with the scholarship process. I got a 4-year scholarship to VMI and just finished getting physically qualified by dodmerb. Got any questions, just ask.
One small reccomendation, DO NOT work out for at least 3 days or so before taking your Dodmerb urinalysis. Working out can cause protein to appear in your urine and if that happens then you'll be asked for a remedial test. Its not that big of a deal but passing the first time can save you sooo much time and it'll give you peace of mind. Still, if you're asked for any remedials, don't freak out, lots of people are asked for then and then either qualified or given a waiver.
Also I remember I was took my eye exam for dodmerb, the guy who did it pretty much half-assed and rushed it (while doing my eye test he kept going online to his myspace!). It also didnt help that I didn't sleep well the night before and my eyes were pretty tried and red from waking up early for the physical. My eyes were found to be 20/40 in both eyes distant and 25/20 in both near. And they were correctable to 20/20 near but only 20/25 distant. The Navy requested a manifest refraction too check my eyes out again. The optometrist I went to actually took their time and did everything properly and I made sure I was well-rest and drank plenty of water (which I hear helps) and turns out I got 20/20 near, and 20/25 distant but it corrects to 20/25. Bottomline, don't worry too much about Dodmerb, but follow what they say carefully and everything will be okay.
