FRAK! One stupid mistake!

So today I went over to a place across the street from DMV that will let you take the test in their car with having to schedule the test and bring your own car. The one problem is that I failed this test because I was two miles an hour over the speed limit in a school zone. TWO! This place has a zero tolerance policy and DMV and the local police check drivers tests for this. So I have to go back next week on tuesday and retake it. I'm going to go five mph UNDER this time just to be safe, because I so want to get this done.
