Welcome to your 2365 602 Electrical Science. This mock exam is not a substitute for proper teaching or revision and should only be used as a resource to prepare learners for the exam. The questions (along with the wording and diagrams) contained within the bank of this exam are purely made up by our lecturers and not copied from any actual qualification exam. So while this is an excellent free revision resource, please do not rely on these exam questions alone to help you be successful within your qualifications. When you are ready, please press "start quiz".
