It doesn’t matter if you don’t remember every direction or if you go the wrong way that can happen to the most experienced drivers.
Independent driving is not a test of how you follow directions. Driving independently means making your own decisions – this includes deciding when it’s safe and appropriate to ask for confirmation about where you’re going.
If you ask for a reminder of the directions, the examiner will confirm them to you. Don’t worry If you go off the independent driving route as it won’t affect the result of your test unless you commit a driving fault. If you go off the route or take a wrong turning, the examiner will help you to get back on the route. You can then continue with the independent driving
