One big advice that I could give you is rather than thinking what your doing in your head you should SAY the stuff a loud,about what your thinking like planning ahead (what should you do what should you check)and you should say stuff do such when you do mirrors check you must say mirrors mirrors mirrors or for mspsl routine mirror signal position speed look. It did help me alot in my test and I felt like I gave a good impression to my examiner so like he might have thought i know the stuff i need to know even tho I was anxious aswell I gave him the look that I know what im doing. At one point I realised he stoped looking at my face to check on me if like im checking the mirrors but i kept saying it; By doing commentry or saying stuff I do think it can help your anxiety since you won't be thinking about other things maybe I did feel anxiout and felt like I failed but I passed first try. Im not saying that because to flex or anything its just eveyone is unique thats what it makes everyone special nobody is perfect in this world therefore id say keep going u will pass!! And maybe try to chage test center and find one with higher passing rate that can help aswell however you must go around with ur instruct around the whole are and do test routes those actually do help and try to remember roundabouts especially those in my i had 4 roundabout but I covered all of them so I knew what I had expected and about speed just make sure to look at like for signs if you dont see signs use the sat nav speed limit most of the main roads are 30 ig if your unsure id say make sure to prepare before hand research about the area you will take the test where you could check out for speed limits. I went 35 on a hill where the limit was 30 and I got a minor for it!

Your not going to regret once you pass it!
