English language requirements for applicants whose first language is not English: IELTS 6.0 overall. Different requirements apply for second year entry, and specified component grades are also required for applicants who require a Tier 4 visa to study in the UK.

Other English language qualifications may be acceptable so please contact us for further details. If we accept the English component of an international qualification then it will be included in the information given about the academic levels listed above. Please note that date restrictions may apply to some English language qualifications

If you are an international student requiring a Tier 4 visa to study in the UK please see our immigration webpages for the latest Home Office guidance on English language qualifications.

If you do not meet our IELTS requirements then you may be able to complete a pre-sessional English pathway that enables you to start your course without retaking IELTS.

Additional Notes

If you’re an international student, but do not meet the English language or academic requirements for direct admission to this degree, you could prepare and gain entry through a pathway course. Find out more about opportunities available to you at the University of Essex International College here.

External Examiners provide an independent overview of our courses, offering their expertise and help towards our continual improvement of course content, teaching, learning, and assessment. External Examiners are normally academics from other higher education institutions, but may be from the industry, business or the profession as appropriate for the course. They comment on how well courses align with national standards, and on how well the teaching, learning and assessment methods allow students to develop and demonstrate the relevant knowledge and skills needed to achieve their awards. External Examiners who are responsible for awards are key members of Boards of Examiners. These boards make decisions about student progression within their course and about whether students can receive their final award.

eNROL, the module enrolment system, is now open until Monday 21 October 2019 8:59AM, for students wishing to make changes to their module options.

Exit awards

A module is given one of the following statuses: 'core' – meaning it must be taken and passed; 'compulsory' – meaning it must be taken; or 'optional' – meaning that students can choose the module from a designated list. The rules of assessment may allow for limited condonement of fails in 'compulsory' or 'optional' modules, but 'core' modules cannot be failed. The status of the module may be different in any exit awards which are available for the course. Exam Boards will consider students' eligibility for an exit award if they fail the main award or do not complete their studies.

Programme aims

The teaching aims of this course are:
- to equip students with the knowledge and skills that are currently in demand in mathematically oriented employment in business, commerce, industry, government service, the field of education and in the wider economy;
- to provide students with a foundation for further study and research;
- to produce graduates who are mathematically literate and capable of producing a logical argument;
- to enable students to acquire a broad understanding of mathematics;
- to provide teaching which is informed and enhanced by the research activities of its staff;
- to encourage students to adopt an investigative approach and develop independent study skills in order to ensure their continuing professional development.

In particular, the programme introduces the students to some of the basic ideas and underlying theory of the mathematics of network security, an area of great importance in the technology of today.

The 3rd year of this degree is spent studying relevant topics at a suitable university abroad.

Learning outcomes and learning, teaching and assessment methods

On successful completion of the programme a graduate should demonstrate knowledge and skills as follows:

A: Knowledge and understanding

A1 Knowledge and understanding of the basic mathematical methods and techniques of linear mathematics, calculus and statistics that underpin the study of more advanced mathematical ideas.
A2 Knowledge and understanding of some of the ideas and methods used in mathematical proof of results in algebra, analysis, and discrete mathematics and familiarity with some specific examples.
A3 Knowledge and understanding of the power and potential pitfalls of computer use and mathematical computer packages, and experience in their use.
A4 Knowledge and understanding of the use of mathematics for modelling and as an investigative tool for the solution of practical problems. An appreciation of the importance of assumptions.
A5 Knowledge of computer networks, the Internet and security issues created by them
A101 Experience of education in mathematics, cryptography and network security in the year abroad.
Learning Methods: Lectures are the principal method of delivery for the concepts and principles involved in A1-A5.
Students are also directed to reading from textbooks and material available online.
In some modules, understanding is enhanced through the production of a written report.
Understanding is reinforced by means of classes (A1-A5), laboratories (A3) and assignments (A1-A5).
A101 is learnt during the year abroad.
Assessment Methods: Achievement of knowledge outcomes is assessed primarily through unseen closed-book examinations and also, in some modules, through marked coursework, laboratory reports, statistical assignments, project reports and oral examinations.
Regular problem sheets provide formative assessment in most modules.
A101 is assessed by passing the year abroad.

B: Intellectual and cognitive skills

B1 Identify an appropriate method to solve a specific mathematical problem.
B2 Analyse a given mathematical problem and select the most appropriate tools for its solution.

The assessment of project work includes specific allocations of credit for the quality of presentations (D1 and D2).


The University makes every effort to ensure that this information on its programme specification is accurate and up-to-date. Exceptionally it can be necessary to make changes, for example to courses, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to courses may for example consist of variations to the content and method of delivery of programmes, courses and other services, to discontinue programmes, courses and other services and to merge or combine programmes or courses. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications.

The full Procedures, Rules and Regulations of the University governing how it operates are set out in the Charter, Statutes and Ordinances and in the University Regulations, Policy and Procedures.
