Any tips for driving test in Edinburgh (Musselburgh)

Hi guys!
I'm having my first driving test next week at Musselburgh. Any tips for any particular hazards/annoying roundabouts to look out for it? I'm booked in for 2PM, so I'm just a bit worried the traffic will be picking up and lots of schoolchildren everywhere + the nerves = total disaster. I do tend to be quite nervous even with my driving instructor, so I'm just trying to figure out most potential things that could mess up my nerves beforehand and this will hopefully make me less nervous on the test day. I've driven around the test centre area, and even the road going out of the test centre is pretty annoying and busy at most times, so I'm just worried I'll fail even before I start my test properly :biggrin:

Also did you have your driving instructor in the car with you when you took the test? I'm not sure I want him to see if I fail massively :/
Any advice much welcomed!
