Patience, Grasshopper
Being on the Register itself is possibly more excruciating than going through the clearances. Being stuck at a certain rank, movement is uncertain and nerve wracking. One week I'm at X out of 200+, and two weeks later I'm further down the list at X+6. It's at this point that I need to leave it in the hands of fate. Obsessively checking my email or refreshing the group when calls begin to go out are less than helpful; all I can do is begin to refresh my CNL and schedule a test (of which I am less than certain of passing) and sign up again for the next FSOT testing window.
It'll either happen or it won't. The aggravating thing is that it's just right there!
