Oh, okay I'm going Navy so PRT.
A lot of people submit without their MEPS physical and their PRT scores. This information though is needed if/once you get pro-rec'd for whatever designator you wanted.
Then upon pro-rec you get your final select after your MEPS,PRT, and security screen is processed and approved.
SOME officer recruiters just feel more comfortable (like mine for instance) about sending the whole thing in with the kit. I'm not sure if having a complete kit at the boards weighs any more than someone who has not done the PRT or the MEPS...(some officer recruiters peruse these threads, maybe they can answer that)...
Point is, it is very normal to submit without the medical and fitness information. Maybe your OR is just hesitant because of your murmur..and he/she just wants to play it safe to make sure you can get a waiver approved.
What designator are you applying for? What are your stats?
