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. 


Compare this course

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.

Find out if you have enough time to study with our time planner

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:

How much will it cost in England?

We believe cost shouldn’t be a barrier to achieving your potential. That’s why we work hard to keep the cost of study as low as possible and have a wide range of flexible ways to pay to help spread the cost.

  • A qualification comprises a series of modules, each with an individual fee. Added together, they give you the total cost.
  • Fees are paid on a module-by-module basis – you won't have to pay for the whole of your qualification up front.
  • Most of our students study part time at a rate of 60 credits a year.
  • Our typical fee for 60 credits is £3,636*.
  • This means, at current prices, the typical total cost of your qualification would be £14,544*.
  • This qualification also includes one or more option modules with a lower-than-typical cost. If you choose to study one of these modules, the total cost of your qualification will be lower.

*The fee information provided here is valid for modules starting before 31 July 2025. Fees typically increase annually. In England, fees are subject to the part-time fee limit, as set out in section C of the University's Fee Rules.

Additional costs

Study costs

There may be extra costs on top of the tuition fee, such as set books, a computer and internet access.

If your income is not more than £25,000 or you receive a qualifying benefit, you might be eligible for help with some of these costs after you start studying.
