Does anyone know how long one is usually at MEPS for? I have a San Diego MEPS appointment set up for next tuesday, and I'll start the process around 545am, and my recruiter told me that I should be out around noon. So does MEPS usually last 6 hours or can it go past that? I went to MEPS when I entered the Navy as an enlisted sailor, but I don't remember it lasting that long. I'm asking because I have a part time job that starts at 2pm, I'm leaning towards just calling my supervisor for the day off.
