Wait, what? You have to book a whole new test? :/ I just go to 'change the date of your practical test' and look for cancellations there. Granted, I haven't gone through with it as I'm actually fine with my test date, but it doesn't make sense that it has an option of changing your test date when logging in with your current ref and driving license number if you have to rebook a whole new test. Could someone clarify for me please?
