This maths diploma has two stages, each comprising 120 credits.
- In Stage 1, you’ll study four 30-credit modules from the default or intensive start.
- In Stage 2, you’ll choose one 60-credit module and 60 credits of option modules.
You’ll study four 30-credit modules from the default or intensive start. Read the Entry requirements section to decide which start is right for you.
Essential mathematics 2 (MST125) includes an online invigilated exam. ProctorU, a service based outside the UK, will remotely invigilate your exam. To study this modules, you must agree to additional Terms of Service. Find out more about online invigilation.
Stage 1 is the same in many of our mathematics and statistics qualifications. So, you could change qualification at this point if you want to.
You’ll choose one 60-credit module and 60 credits of option modules.
We regularly review our curriculum; therefore, the qualification described on this page – including its availability, its structure, and available modules – may change over time. If we make changes to this qualification, we’ll update this page as soon as possible. Once you’ve registered or are studying this qualification, where practicable, we’ll inform you in good time of any upcoming changes. If you’d like to know more about the circumstances in which the University might make changes to the curriculum, see our Academic Regulations or contact us.

Accessibility
We make all our qualifications as accessible as possible and have a comprehensive range of services to support all our students. The Diploma of Higher Education in Mathematical Sciences uses a variety of study materials and has the following elements:
- printed material
- online material, including websites, audio/video media clips, and interactive activities
- using mathematical and scientific expressions, notations and associated techniques
- using and producing diagrams and screenshots
- small amounts of practical work and other activities, such as group work with other students on some modules, writing short reports or preparing presentations
- using specialist software
- online tutorials
- continuous and end-of-module assessment in the form of short and long answer questions, and in most cases an examination
- using feedback: continuous assessment involves receiving detailed feedback on your work from your tutor and using this feedback to improve your performance
- engagement with learning and assessment within a pre-determined schedule or timetable – time management will be needed during your studies and the University will help you to develop these skills throughout your qualification.
For more detailed information, see the Accessibility Statements on individual module descriptions. If you feel you may need additional support, visit Disability support to find more about what we offer. Contact us as soon as possible to discuss your individual requirements, so we can put arrangements in place before you start.

Credit transfer
If you have already studied at university level, you may be able to count it towards your Open University qualification – which could save you time and money by reducing the number of modules you need to study. At the OU we call this credit transfer.
It’s not just university study that can be considered, you can also transfer study from a wide range of professional or vocational qualifications such as HNCs and HNDs.
You should apply for credit transfer before you register, at least 4 weeks before the registration closing date. We will need to know what you studied, where and when and you will need to provide evidence of your previous study.
For more details of when you will need to apply by and to download an application form, visit our Credit Transfer website.
On completion
On successfully completing this course, we’ll award you our Diploma of Higher Education in Mathematical Sciences.
International recognition
If you intend to use your Open University qualifications to seek work or undertake further study outside the UK, we recommend checking whether your intended qualification will meet local requirements for your chosen career. Find out more about international recognition of Open University qualifications.
Regulations
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.
There is no formal pre-requisite study, but you must have the required mathematical skills.
You have a choice of starting module depending on your current skill level: Discovering mathematics (MU123) or Essential mathematics 1 (MST124). You can find out which module is your best starting point here.
You can also check you’re ready for MU123 or MST124, and the topics they cover, at the link above.
How much time do I need?
This depends on your level of prior knowledge of mathematics and, in general, we recommend that you build up your pace of study slowly to ensure you gain a good understanding of the more basic topics. How many credits you can complete in a year will depend on your study situation, and this qualification is designed to enable you to vary your study intensity from year to year.
- Most of our students study part time, completing normally 60 credits a year.
- This will usually mean studying for 16–18 hours a week.

Your full-time equivalent study intensity options in Stage 1 depend on which start you choose.
Default start
You cannot complete Stage 1 in one year. You may only begin MST124 after you finish MU123.
Intensive start
To complete Stage 1 in one year, you must begin with MST124. You may start your other Stage 1 modules at the same time (or the following February if you start MST124 in October, and your option modules have a February start).
Preparing for study with an Access module
Students who start their study with an Access module are more likely to be successful when they advance to Stage 1 of their qualification. They’re specially designed to give you a gentle introduction to OU study, boost confidence in your study skills, and help you gain a broad overview of your chosen subject area.
You’ll also benefit from:
- feedback from your tutor through regular one-to-one phone tutorials
- support from a dedicated team throughout your study
- detailed written feedback on your work.
The Access module we’d recommend studying in preparation for this qualification is our:
Science, technology and maths Access module
What you will study
This multidisciplinary module is an ideal starting point if you have little or no previous knowledge of the sciences, technology and mathematics. It’ll help develop your study skills in advance of your OU qualification, and you get to explore a number of STEM subjects including science, engineering and design, environment, mathematics, and computing and IT.
