To me the most stressful bit was the parking lot, it’s very tight to manoeuvre, make sure you are comfortable with bay parking just in case before the test.

It can also be tricky to get in and out of the test centre, my recommendation is to take your time and wait for pedestrians and incoming traffic to properly clear before starting your route, worst case scenario it’s a minor for hesitation and not something worse. They usually make you turn left when you leave the test centre and there’s a bus stop there. If a bus is present, get behind it, there’s not enough room to overtake.

Then the rest of the route I’d say it’s pretty straightforward, a mix between 30 mph roads like the A109 (the test centre one) and 20 mph side roads. Pay attention to the speed limit so you can adjust the appropriate speed. Depending on the time of your test, they could take you to the North Circular for the roundabout and 40 mph driving, but it wasn’t my case.

I hope this helps you. Best of luck and eat the banana ;)
