Show me, tell me
During your driving test you will be asked a 'show me' and a 'tell me' question, these relate to the mechanics of the car. For example, the examiner could ask you to identify where the windscreen washer reservoir is in the car and then ask for you to 'show' them how you'd check the windscreen washer level.
I will go through all of the questions before you go in for your test so there's nothing to worry about. But even if you did answer both of these questions wrongly, you would still only be marked with one driving fault.
For sample questions I'd recommend looking on YouTube.
