Computer Science lessons usually begin with a friendly low stakes quiz, retrieval practice, or, as we move through the course, an exam style question. This is based upon the preview work that is set each week, or from a previous topic from earlier in the course. We build on the preview exercises by introducing new concepts and then doing a variety of activities to embed your understanding and clear up any misconceptions. We work in pairs, groups and individually; this depends upon the activity and if we are doing theory or programming. The kind of trips you can expect to go on are university visits for students who want to understand what it will be like to study beyond A-level, but we also get to see technology in action at businesses, expos and museums (both locally and further afield).
