The course has been written by Simon Ogborn FIET MSET LCGI, owner and lecturer at Erudite Training Ltd.
Simon has been an electrical engineer for over thirty years, primarily working on critical power supplies within petrochemical plants. After attending college in 2004 to take his Design and Verification qualification, in which he attained a Distinction, he was asked to join the teaching team at Tameside College. Simon started Erudite Training in 2009 with the primary ethos being to teach the subject properly, not just coach for exams. This, in turn lead Simon to be head hunted by City and Guilds, in 2013, to become one of their Technical Consultants.
Simon has been involved in many of the electrical qualifications since then, including working on the 2396 Level 4 Design and Verification. He is therefore ideally placed with technical understanding, teaching skills and the valuable insight into what errors candidates make in their exams.
