Mathematics shapes our world – from algorithms that power social media to the sat nav in our cars. With our accredited mathematics degree, you’ll gain the skills and expertise to solve real-world challenges from the everyday to the complex. This course will expand your knowledge of pure and applied mathematics, with the option to study statistics, physics, maths education and more. You’ll develop the problem-solving, logical reasoning and analytical skills of a mathematician – abilities highly valued in careers from business to banking and data science to teaching.
This course is accredited by:
Institute of Mathematics & Its Applications logo
Stage 1 of this degree is the same as our Certificate of Higher Education in Mathematical Sciences (T14) and Stage 1 of our Diploma of Higher Education in Mathematical Sciences (W43), BSc (Honours) Mathematics and Statistics (Q36) and BSc (Honours) Mathematics and its Learning (Q46).
This maths degree has three stages, each comprising 120 credits.
You’ll choose one of two starts depending on your level of mathematical knowledge: the default start enables you to build up skills, knowledge and confidence at a slower pace, the intensive start allows you to build on your existing mathematics study. Read the Entry requirements to decide which start is right for you.

Your honours classification (first, upper second, lower second or third class honours) will depend on the grades you gain at Stages 2 and 3.
You'll also have the opportunity to attend a degree ceremony.
If you plan to work or study outside the UK, we recommend checking whether this qualification meets local requirements. Find out more about the international recognition of Open University qualifications.
As a student of The Open University, you should be aware of the content of the qualification-specific regulations below and the academic regulations that are available on our Student Policies and Regulations website.
We regularly review our curriculum to keep it up to date. This means the structure, availability, and content of the course or modules may change. We’ll update this page as soon as possible if there are any changes. If you have already registered for this qualification, we’ll inform you in good time of any upcoming changes where practicable. For more details, see our Academic Regulations or contact us.
You can achieve this degree in as little as three years and have a maximum of 16 years to complete it. Our module-by-module approach gives you the flexibility to complete your qualification at a pace that works best for you.
If you choose the intensive start, you can complete this degree in three years by studying at a pace equivalent to full-time. That’s similar to a student at a campus-based university.
If you choose the default start, you can complete this degree in four years by studying Stages 2 and 3 at a pace equivalent to full-time. That’s similar to a student at a campus-based university. You’ll study Stage 1 part-time. That’s roughly half the rate of a student on a full-time course at a campus-based university.
If you choose either start, you can complete this degree in six years by studying part-time. That’s roughly half the rate of a student on a full-time course at a campus-based university.
At the OU, flexibility and support go hand in hand. You’ll be in control of when and where you study, with clear deadlines to guide your progress. Whether you’re balancing work, family or other commitments, our approach helps you fit learning into your life. Students consistently praise the support we provide, and from the very start, you’ll be part of a vibrant OU learning community.
As you progress through your qualification, you’ll have access to a dedicated online study space, expert tutor guidance, optional live tutorials, and a wide range of resources to help you succeed. The sections below outline what you can expect.
Your module website will be a central hub for your learning, giving you easy access to:
Discover how the OU’s module websites, course materials, and support tools help you study online with confidence.
Each module has a dedicated tutor who will guide you through your studies. They’ll provide feedback, help you find resources, mark your assignments and support your learning journey.
For extra support, you can attend optional live tutorials with your tutor. These are usually conducted online, and most are recorded so you can review them later.
