Completion and certificate

Complete every required lesson in your learner account to become eligible for a private GEC Certificate of Completion. The quizzes are formative self-checks unless the course page expressly states otherwise. The certificate records completion of this GEC learning programme; it is not an Ofqual-regulated qualification, RQF award, academic credit or professional licence.

How to study

Work through the lessons in order on a current browser. Keep brief notes and save only non-sensitive project material. Product interfaces and industry practices change, so confirm important technical steps in current official documentation.
