Depends on the country, I guess Over here in the UK, I had one multiple choice test, then the practical driving test, and passed them both first time. I think it's changed to two tests before the practical now, I don't know, but I know someone who recently tried the practical and failed for their third time now

Are you in the US? You'll have it easy then, with the lack of roundabouts there, I think you only have something like two in the entire country or something
