I remember taking my N test. I had taken a few lessons with an instructor beforehand so I felt well prepared. Then I get into the car and the test taker starts asking me to roll down the window, do the turning hand signs, and then asks me to turn on the high beams. I never learned what all the knobs were in the car. I never asked and nobody mentioned it. I knew the turn signals and how to turn the car on and off. I had never driven with the high beams (knowingly 😅). I think I turned and pushed every knob by the steering wheel and cleaned the back window before the blue light came on. Moral of the story, learn all the buttons in the car, it’s important and it’s part of the test 🙈
