Accessibility

We make all our qualifications as accessible as possible and have a comprehensive range of services to support all our students. The BSc (Honours) Combined STEM degree uses a variety of study materials and may have the following elements, depending on the modules you choose:

  • studying online – some modules have a mixture of printed and online material, and others are entirely online. Online learning resources may include websites, audio/video media clips, and interactive activities such as online quizzes
  • online tutorials
  • using mathematical and scientific expressions, notations and associated techniques
  • working in a group with other students
  • using and/or producing diagrams and/or screenshots
  • practical work
  • finding external/third party material online
  • using technology for research purposes involving access to catalogues and databases online
  • working with specialist reading material such as works of art and musical manuscripts
  • continuous and end-of-module assessment in the form of essays, short answer questions, and in some 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 degree
  • some modules may require you to use specialist software
  • using an online laboratory or design/engineering studio.

All qualifications require you to complete learning and assessment activities within a required timescale and according to pre-determined deadlines. You will therefore need to manage your time effectively during your studies and the University will help you to develop this skill throughout your degree. Information on assessment will be available to you at the start of each module.

Credit transfer

If you've already completed some university-level study somewhere else, you may be able to count it towards this 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. For more details and to download an application form, visit our Credit Transfer website.

Classification of your degree

On successfully completing this course, we’ll award you our BSc (Honours) Combined STEM.

The class of honours (first, upper-second, lower-second or third) will depend on your grades at Stages 2 and 3.

You’ll have the opportunity to attend a degree ceremony.

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 £3,892*.
  • This means, at current prices, the typical total cost of your qualification would be £23,352*.
  • 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 2026. Fees typically increase annually. In England, fees are subject to the part-time fee limit, as set out in section 5 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.

Field schools

This qualification has modules (S209, S226 or S286) with optional residential field schools. You must pay an additional charge for each residential school and your travel. See individual module descriptions for more information.

  • They can be made up of essays, questions, experiments or something else to test your understanding of what you have learned.
  • Your tutor will mark and return them to you with detailed feedback.

End-of-Module Assessments

  • The final, marked piece of work on most modules.
  • Modules with an end-of-module assessment won’t usually have an exam.

Exams

  • Some modules end with an exam. You’ll be given time to revise and prepare.
  • You’ll be given your exam date at least 5 months in advance.
  • Most exams take place remotely, and you will complete them at home or at an alternative location.
  • If a module has an in-person exam (that you must take at one of our exam centres) or is invigilated online, we’ll make this clear in the module description.
