My instructor was pretty chatty but I found that since you’re focusing so much on driving, your brain forgets to stutter. Let your instructor know you’ve got a stutter and if you’re still struggling to say your name, pull out your provisional license and point at your name I’m sure you’ll be completely fine. You’ll end up talking about random stuff. Mine used to be a massive stoner so we spoke about bongs and stuff lol Good luck and keep us posted 👌🏼
