We have been trying to book a test for a few weeks and the test centre near us never ever ever has any slots available. We've tried 6am Monday morning and throughout the day. Do the app things work? Which one to try? We are in the south east, outside London and want the test to be at a certain test centre so the learner can practice in that area. I have seen tests in other parts of the country, is it a problem everywhere or just in our area? Suggestions? Do you have to go through all this again if you fail? It's ridiculous.
