Specification overview
The OCR Level 3 Core Maths A (MEI) qualification builds on GCSE mathematics to promote mathematical thinking and fluency in real-world contexts. It is designed for learners who are not studying A Level Mathematics but need to apply maths in other subjects such as biology, geography, business, psychology or economics. The course develops skills in reasoning, problem-solving, data interpretation and modelling. It equips students with practical and analytical tools to make informed decisions and confidently tackle everyday mathematical challenges.

Key tips for success
Doing well in your OCR Level 3 Core Maths A (MEI) 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.
