An overview of the qualification and what candidates must know in order to complete each unit. Clear guidance on how to carry out all the activities, from opening the appropriate software package to changing the look of a graph, adding a new slide to a presentation or inserting the correct picture into your publication. Exercises offering student the chance to practise their skills. An opportunity to work through entire assignments. Set out in the same format as the final assessment, these also provide model answers and can be compared with students' own work to establish where marks might have been lost. Help in avoiding mistakes: some of these, known as critical errors, mean instant failure. Within each chapter, we've highlighted the critical errors and summarised at the end. A final, self-assessment checklist for each unit allows assessment of your own skills to ensure that there are no gaps in knowledge or capabilities. A comprehensive glossary so all the technical terms and computer jargon mentioned in the book are clearly understood.
