How many times can you fail the written permit test?

Well if you fail twice in a row. You shouldnt go for a third time until you make sure you'll pass. Why waste money? (Also there are no indications of a limit, possibly for so many within short time span)

No clue.. How hard can it be? Book isn't that thick!

Thanks, I received this question today and had no idea.. Will pa6y up the response

I'm not sure. You'll have to check with Penn Dot
