Lee focused on educating as opposed to just trying to pass the exams, learnt a lot more than required to just pass the course, really beneficial

Came into the course with a basic knowledge of HV operations. Lee structured the course perfectly, the pace, the delivery and the ease of understanding. Couldn’t fault him at all or the facilities. High calibre of trainer!
