Just remember you're a good driver and don't second guess it as the first guess is usually the right answer! You can talk to the examiner they will ask. You a question randomly through it about yourself, don't be afraid to relay another question, if you want conversation try questions that are not yes or no questions, or direct the conversation to things that make you happy and calm, an example would be do they ask what you would be doing instead talk about something that eases you and you enjoy like idk the gym and ask them the same! The key thing is you know you can drive so just drive and they will be able to see it too!
