Fantastic and worth every penny. I used for the first time on my 2nd test and the waiting list was 8 weeks. Within 3 days speedy test text me and took 6 weeks off my wait. I didn't pass so went through the same procedure and this time it was a 9 week wait. In a few days speedy test found a cancellation and i was back for my 3rd test 2 weeks 2 days after the 2nd test. Then i passed so very happy with speedy test as it knocked off 7 weeks. I had 3 tests in 7 weeks. Well worth £21.00. Also great thing with it is you only pay once, it doesn't matter how many times you fail.
