Computer Science A level is not just about learning to use tools or training in a programming language, instead the emphasis is on computational thinking. Computational thinking is a kind of reasoning used both by humans and machines and is an important life skill. Thinking computationally means using abstraction and decomposition. The study of computation is about what can be computed and how to compare it. Computer Science involves questions that have the potential to change how we view the world. Students will develop skills of analysis and problem solving throughout the course.
