Can I do the 18th edition with no experience?

While the course is aimed at anyone with a good working knowledge of electrical installations, the course is primarily intended for practising electricians and those in allied professions. Previous knowledge of the regulations is not essential, but you will need a fundamental knowledge of electrical principles.

What should I do to pass?

Make sure you have a thorough understanding of each section of the regs – the exam is open book, but you won’t have long per question (two minutes exactly), to find the answer. Having a comprehensive knowledge of what each section is about will save you valuable time in the exam.

Get your hands on a few mock exams – these are invaluable tools to identify your weaknesses, which you can strengthen with targeted revision. They’ll also help you get used to the format and style of the questions ahead of your exam.

Tailor your revision to your learning style; more of an auditory learner? Record yourself reading out revision cards or watch YouTube videos. Prefer visual cues? Get out your highlighters and get to drawing tables, mind maps, and diagrams to help memorise the information.
