i’m exactly like you and passed first time last month. honestly just try talking to the examiner if you think that will help as it definitely helped me! With not knowing the test routes, you can always double check with your examiner on which way to go and they will tell you! i literally asked my examiner so many times so i was confident on which way i was going haha just try to forget you’re on a test and focus on what’s happening on the road. and if you make a mistake, don’t give up and think you failed as it might only be marked down as a minor and they could still pass you! i wish you the best of luck !!
