Who is the course for?
This course is designed at GCSE-Level to A-Level educators and learners. This course has a focus on supporting educators looking for an engaging way of teaching GCSE Computer Science concepts.
We recommend that learners have a basic understanding of Python, for example gained from our Programming 101 course for beginners
An understanding of binary is helpful but not necessary (you may be interested in our How Computers Work course)
Due to its section on the representation of images, this course includes several steps and questions based around visual content.
