My passed in December.
He had about 6 months of lessons once a week and practice with a car on a regular basis and was a pretty confident driver.
I think your chances with 5 lessons and no practice are I'm afraid non-existant.
there is also now a section where the examiner tells to to take him somewher by the road signs and you have to navigate and drive whist he watches.
Your main problem is that there are a number of test routes and a local instructor will know them and take you on them so that you become familliar with them
