    About WJEC GCSE Physics

    The WJEC GCSE Physics qualification invites students to explore the fundamental principles that govern the natural world, from the tiniest subatomic particles to the vastness of space. Designed to foster curiosity and a methodical approach to problem-solving, this two-year course builds a solid foundation in core physics concepts while developing practical skills through hands-on investigation. Students will learn to apply mathematical and analytical techniques to explain phenomena such as electricity, forces, waves, and nuclear processes, preparing them for further study or the demands of STEM-related careers.

    Structured to be accessible and engaging, the specification emphasises the relevance of physics in everyday life and sustainable futures. It aligns with the broader WJEC Science suite, providing a coherent progression from Key Stage 3 and clear differentiation between Higher and Foundation tiers. The content is grouped into logical units, allowing learners to see connections between topics like energy transfers, motion, and the electromagnetic spectrum. Throughout the course, students are encouraged to evaluate scientific information critically, an essential skill in an age of rapid technological change.

    Practical work is woven throughout the teaching content, with a set of required practicals that must be undertaken in the laboratory. These experiments are not assessed separately but directly examined within the written papers, ensuring that understanding of experimental methods and data analysis is integral to achievement. This approach reduces the assessment burden while still rewarding genuine investigative skills. Overall, the WJEC GCSE Physics course offers a balanced mix of theoretical knowledge and applied understanding, equipping students with a lifelong appreciation for how physics shapes our universe.

    Assessment Structure

    The qualification is assessed through two written papers at the end of the course, each contributing 50% of the total marks. Both papers are 1 hour 45 minutes long and contain 80 marks, giving a total of 160 marks for the whole GCSE. The papers cover distinct but interconnected topics: Unit 1 focuses on Electricity, Energy, and Waves, while Unit 2 covers Forces, Motion, Space, and Radiation. Each paper includes a range of question types—multiple choice, structured, closed short-answer, and extended response—and there is no separate coursework or practical exam. Practical skills are instead assessed through exam questions that draw on the laboratory work carried out during the course.
