I found Mark to be a very professional, calm and friendly instructor. After years of thinking that I would never be a driver, I'm so glad I've finally passed my test, and Mark provided the tutoring and encouragement I needed. I was quite a nervous learner but Mark was very realistic about what could be achieved; he was also very patient and always offered sound advice.
The LDC system was great for me because the workbook allowed me to read and prepare for each topic before the actual lesson, and I found the whole process far less daunting to know what I was doing in my head before attempting it in the car.
All in all, I wouldn't hesitate to recommend Mark and the LDC system.
