An image to illustrate the MSc in Mathematics
Advance your career with a high-level qualification. Delve deep into the aspects of pure and applied mathematics that interest you, such as fractal geometry, coding theory, or even quantum physics. Choose from a wide range of modules; there are topics for not only mathematicians but also mathematically inclined engineers and scientists. To conclude, you’ll complete an independent study, exploring a topic in detail and submitting a dissertation.
The first two-thirds of this MSc are the same as our Postgraduate Diploma in Mathematics (E23). The first third is the same as our Postgraduate Certificate in Mathematics (C90).
To gain this qualification, you need 180 credits. You'll choose one 30-credit core module, 120 credits from a range of option modules, and complete your degree with a 30-credit dissertation module.

By studying the MSc in Mathematics, you’ll:
You’ll study flexibly online with expert tutor support, tutorials and extensive digital resources.
You’ll be awarded a Master of Science in Mathematics upon successful completion. You’ll be entitled to use the letters MSc (Maths) (Open) after your name.
Your masters degree may be awarded with a distinction or a merit. The qualification regulations explain the criteria you’ll need to meet to earn one of these classifications.
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.
Most students study the MSc in Mathematics part-time, completing 60 credits per year over a three-year period. Typically, this translates to 16–20 hours of study per week.

You can also complete this qualification in two years by studying three modules concurrently each year. If you wish to stay at this faster rate, you’ll need to devote 32–40 hours each week to your studies.

The recommended hours include time to work through that week’s online study planner, complete recommended reading, and attend tutorials.

There is no time limit within which you must complete the MSc in Mathematics.
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.

You may be eligible for:
Mathematics postgraduates can be found throughout industry, business and commerce, in the public and private sectors. Employers value the intellectual rigour and reasoning skills that mathematics students can acquire, their familiarity with numerical and symbolic thinking, and their hallmark analytic approach to problem-solving.
There are a variety of reasons for studying mathematics at postgraduate level. You may want a postgraduate qualification to distinguish yourself from an increasingly large pool of graduates. You may find that your undergraduate mathematical knowledge is becoming insufficient for your career requirements, especially if you are hoping to specialise in one of the more mathematical areas, which are becoming more sought after by employers. Or you can move on to a PhD in Mathematics. The range of opportunities is vast, and mathematics postgraduates are equipped with the skills and knowledge required for jobs in fields such as finance, education, engineering, science, and business, as well as in mathematics and mathematical science research.
Once you register with us (and for up to three years after you finish your studies), you’ll have full access to our careers service for a wide range of information and advice – including online forums, website, interview simulation, vacancy service, as well as the option to email or speak to a careers adviser. Some areas of the careers service website are available for you to see now, including help with looking for and applying for jobs. You can also read more general information about how OU study enhances your career.
