ELECTRICAL COMPREHENSION TOP TIPS
The following is a list of key bullet points that we believe will assist you through the preparation period of conducting an Electrical Comprehension test. There are more top tips and advice in our guide which we highly recommend on reading to ensure you are fully equipped for the entire process.

Carry out lots of sample testing questions which focus on the subject you are preparing for. In regards to electrical tests, it is vitally important that you understand what the question is asking. You need to read the question carefully to ensure you have read it correctly.
TOP TIP 2
Whilst undertaking sample tests, it is important that, if you get a question wrong, you spend time working out why you got it wrong. Within this guide, we have provided answers and detailed explanations to assist you through your learning process. If you get a question wrong, consider ‘why’ you have got it wrong. Read through the answers and explanations in order to improve your overall knowledge.

When practising, you must ensure that you work on your speed as well as your accuracy. Most tests are administered under time limits, and therefore you will be expected to answer as many questions as possible within the allotted time given. Having said this, you do not want to sacrifice the accuracy of your answers. Do not rush through the questions; you want to avoid making careless mistakes.
