What is the exact process for creating a package to become accepted for OCS?  I went through some initial paperwork with my recruiter, but that's as far as I have gotten.  If any of you could give me an idea of the tests that have to be taken, what they are like, and how long they take to complete, I would appreciate it.  I know that I have some time because I have to get PRK first, but any information and advice is appreciated.
