Specification overview
The WJEC Eduqas GCSE in Mathematics provides a coherent, broad and satisfying course, designed to encourage learners to build confidence, develop mathematical fluency and appreciate the relevance of mathematics to real-world situations. It aims to prepare learners for progression to A level Mathematics and related study, while also ensuring those not continuing further gain functional competence.
It enables learners to: • develop fluent knowledge, skills and understanding of mathematical methods • select and apply techniques to solve problems • reason mathematically and draw conclusions • interpret and communicate mathematical information effectively
Problem solving is central to this qualification, encouraging learners to apply knowledge across topic areas. The specification supports teaching in varied styles and connects different areas such as algebra and graphical representation.

Key tips for success
Doing well in your WJEC Eduqas GCSE Maths isn't just about how much you study, but how you study. Here are a few proven tips to help you stay on track
- Start with a clear plan: Break the subject into topics and create a revision schedule that allows enough time for each. Start early to avoid last-minute stress.
- Focus on understanding, not memorising: Use our revision notes to build a strong foundation in each topic, making sure you actually understand the material.
- Practise regularly: Attempt past papers to familiarise yourself with the exam format and timing. Mark your answers to see how close you are to full marks.
- Be strategic with your revision: Use exam questions by topic to focus on weaker areas, and flashcards to reinforce important facts and terminology.
- Learn from mistakes: Whether it's from mock exams or practice questions, spend time reviewing what went wrong and why. This helps prevent repeat mistakes in the real exam.
- Stay balanced: Don't forget to take regular breaks, eat well, and get enough sleep, a healthy routine makes revision much more effective.
With the right approach and consistent practice, you'll build confidence and improve your chances of exam success.
