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.

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

*You can complete your studies in six years part-time and three years full-time. However, your last module (SXB390, SXC390, SXE390, SXG390, SXH390 or SXP390) ends in September, so you’ll receive your final results in late October rather than June/July. You should consider this if you’re planning further study and wish to use your BSc (Honours) Natural Sciences as an entry qualification.

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 will I study this course?

With our unique approach to distance learning, you can study from home, work or on the move.

You’ll have some assessment deadlines to meet, but otherwise, you’ll be free to study at the times that suit you, fitting your learning around work, family, and social life.

For each of your modules, you’ll use either just online resources or a mix of online and printed materials.

Each module you study will have a module website with

a week-by-week study planner, giving you a step-by-step guide through your studies
course materials such as reading, videos, recordings, and self-assessed activities
module forums for discussions and collaborative activities with other students
details of each assignment and their due dates
a tutorial booking system, online tutorial rooms, and your tutor’s contact details
online versions of some printed module materials and resources.

If you have additional needs, we can also provide most module materials in alternative formats. Find out more about materials on our accessibility webpage.

Tutor support

You’ll have a tutor for each module, who will introduce themselves before the module begins.

Throughout the module, they will:

mark your assignments and give feedback to help you improve
guide you to learning resources
support you, whether with general study skills or help with a specific topic.

Tutorials

Tutorials usually take place online, and they’re always optional.

Online tutorials are live presentations with module tutors in dedicated online tutorial rooms and are sometimes recorded.

Assessment

Our assessments are all designed to reinforce your learning and help you show your understanding of the topics. The mix of assessment methods will vary between modules.

Computer-Marked Assignments

Usually, a series of online, multiple-choice questions.

Tutor-Marked Assignments

You’ll have a number of these throughout each module, each with a submission deadline.
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.

Progressing to a point where I felt more comfortable writing my assignments, and having my scores reflecting that, made me quite happy because it showed the hard work was being rewarded.
