I encountered a very unpleasant situation yesterday in which I realized that my driving instructor had canceled the test with me. I waited for him for a very long time but he never came without even calling me beforehand. Have you ever encountered this?
OK, this is a pretty common problem where you can have important information using only one resource. This can be found at https://driving-test-cancellations.com and in this matter, it will prove to be the most appropriate and effective means. I'm sure it will work for you next time, but I wish you get your driver's license sooner rather than later.
