$2,500 for many hours of driving school (theory + practice) and the tests. Mostly for the driving school.
The tests alone: Theory - $30, Driving - $150 (both appr.)
Correct me on this, but my understanding is that failure of either test requires a repeat of the course.
It was explained to me this way during a discussion with a hotel clerk in Hamburg; a friend of his was going back through it all for the FOURTH time, at a total cost of some $10,000.00.
