Said I could come back the next day, as it turned out I was busy that day so I passed the following day instead. I failed because I got over confident backing out of a parking spot an nudged a cone. Or, as he put it, I murdered a toddler. Fair enough. We did the backing up thing first so I could get that out of the way, the rest of the test was easy.
I've never heard of a weird secret code to force you to fail, just relax and don't run over any toddlers, I mean cones, and I'm sure you'll be just fine!
Maybe try changing her litter? Sounds like she doesn't like it.
