Well, I guess I didn't get it

I had written a test for a 911 dispatcher position with the City I work for. Sounds pretty sweet eh? Great paying for a person in my position. Money is tight and I was very much looking forward to the possibility of starting a new career.
The testing happened on Tuesday and I studied quite hard. My life was on hold for a while (chores, school work and sanity) for this test. I knew it would all be worth it in the long run, so there were no worries.
After the test, the HR woman said that if I got a call before the end of Friday that would be good, and I would proceed to the next level starting on Monday. If not, then I would get a letter next week...Which would be bad.
While there are technically 1.75 hours left in the day, I've lost hope and succumbed to the fact that I didn't get the passing mark they required. To say I'm disappointed is an understatement. I cant' even express how I feel anymore. I tried a similar test last year and got 69% out of the required 70%. Yes. That's right. 69%. When you have 69% and there are 575 people writing for 3 positions I suppose you have to draw the line somewhere.
I go on; it's not fair; but I go on.
What else can I do?
