To be fair most of us just turned up at the "exam", Watty. When I done mine the supervising Garda told us to just raise our hands if we had any questions. As I had some previous in sitting exams conducted by a professional body I assumed he meant questions relevant to procedural matters... not so he provided individual assistance to any man who raised his hand ranging from adding up the extras that would be displayed on a meter in the (then) Dublin taximeter area to naming roads on common routes. Frankly, it was a farce... and we had no Google Maps or Garmins back then. We had to learn from our clients and follow printed maps, sometimes with nothing more than a lamppost number on some obscure country lane to find!
Give it back to the Gardai, I say.
