As Robthestudent says, PAT have one of the best pass marks in the country,however,a very important factor,they acheive it with regard for minimum hours and respect for the student.
It's easy to look at pass results from schools who harp on about pass rates but have no regard for either of these factors,and get roped in to something you will regret.
Value comes in the form of many factors,not simply the bottom published price.My advice - P.A.T.
