I would definitely recommend Clive as a driving instructor. He taught me to drive in 52days, and I passed my test first time! People thought it impossible for me to learn so quickly, even bet against it, but Clive's dedication meant I was confident throughout my test. He was understanding of how I learnt and knew which skills I needed to practice. I was also grateful for how often he asked what I wanted to do and which bits I wanted to practice.
I learnt before Clive used the LDC system but he has told me about it and it sounds great - who knows how quickly I'd have passed if I did use it!
