I took a semi-intensive course of 20 hours, over 6 sessions, after several months of weekly lessons with another instructor.
I was able to book both the driving lessons and the practical test through StreetDrive, which was very helpful.
"Shaun" improved my driving straight away and I passed the practical test "first time" at the end of the course. He was friendly and helpful throughout and I enjoyed the lessons. Passed - 6 Jun 2016.
