We over-heard the stories how some of our students went to other driving schools, paid the money, and could not pass the driving test. And we are limited in availability so cannot help everyone.
With that in mind, may I suggest you ONE simple idea to evaluate how good the driving school is: Ask them for any recent P test score sheet, if they can show you plenty of them, this school must be good; if not, think twice before handing your money over. :=)
