So the odds of getting it within 950 tries by just guessing are about one in 6,410. So it would appear that she did actually learn something during the process. That, or she just got really, really lucky. I'm getting 29 million as the expected # of tests she would have to take. | ||

Five times and I might start mixing questions into conversation. $100+ and I'd get a tutor. $1000+ and I would have thought more about how well this selling fruit out of my car thing was gonna make me money. The things people do to get an unemployment check??? | ||

The written part isn't even that hard! Anyways, seeing how she did on the written test, theres no way she'll pass the driving part unless she has been doing it illegally. | ||

The record for failing the California bar exam is something like 40 times. Most states limit you to 3-4 fails before you're barred for life from taking the exam again, but California doesn't care. | ||

In any case, upper age limit would be unfair for the many millions of people who can drive quite competently beyond that age limit. My great grandfather drove until he was 100 years old and never had an accident. Should he be confined to his house for the last quarter of his life because some other old people can't drive? Should some 15 year olds be punished because the majority of people that age can't drive? Yes. That's why regulations are in place... | ||
