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.

Having a course that was really varied and studying in a style that worked for Nick, was key to him launching his own business and becoming an entrepreneur.

Skills for career development

By the time you achieve your qualification, you’ll be an adaptable graduate with a range of transferable skills that are highly valued in the labour market – such as analytical, numerical and communication skills, teamworking, problem solving and proficiency in using computers. You’ll also have a good understanding of where your strengths and interests lie, and be well prepared for your next step – whether it’s further study or employment.

Employers also look for evidence of experience of the workplace to support the skills gained through the degree. To succeed, graduates will need to be flexible and multi-skilled, with the ability to work in a multidisciplinary environment.

Career relevance

Chemistry graduates are well placed to enter both scientific and non-scientific jobs. The logical, reasoned approach needed for science study is relevant to a wide range of financial, business and public sector employment, so graduates – particularly those who have good communication and interpersonal skills – are in demand.

Growth areas are predicted to be: environment, energy and sustainability; biotechnology and biomedical engineering; healthcare; telecommunications; pharmaceuticals; bioinformatics; and technology transfer (transfer of scientific expertise to commercial products).

Employers include central and local government, the NHS, the water industry, food and drink companies, media and communications, the horticultural industry, multinational oil companies, the pharmaceutical industry, conservation bodies and universities – in roles such as:

  • research and investigation
  • product design and development
  • analysis and diagnostics
  • science information management
  • science communication
  • scientific sales
  • exploration and extraction of natural resources
  • health and healthcare related professions
  • waste management, recycling and sustainability
  • environmental management, protection and conservation
  • teaching (science is a shortage subject at secondary school level, so there may be incentives to train as a chemistry teacher).

Exploring your options

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.
