Open University in Ireland


MSc in Mathematics
Delve deep into the aspects of pure and applied mathematics that interest you. Choose from areas such as fractal geometry, coding theory and calculus of variations. Advance your career with a high-level qualification. Choose from a wide range of modules. There are topics for not only mathematicians but engineers and mathematically inclined scientists. You'll conclude with an independent study, exploring a topic in detail and submitting a dissertation.

Key features of the course
• Ideal for mathematically inclined scientists and engineers as well as mathematicians.
• Extends your knowledge and refines your abilities to process information accurately, and critically analyse and communicate complex ideas.
• Develops an enhanced skill set giving you an advantage in careers beyond mathematics, such as education, computer science, engineering, economics and finance.
• The UK's most popular MSc in Mathematics.

Subjects taught

To gain this qualification, you need 180 credits as follows:
30–60 credits from:
Entry-level modules
• Calculus of variations and advanced calculus (M820) 30
Next start: 01 Oct 2022
• Analytic number theory I (M823) 30
Next start: 01 Oct 2022

90–1501 credits from:
Intermediate-level modules
• Advanced mathematical methods (M833) 30
Next start: No current presentation
• Analytic number theory II (M829) 2, 30
Next start: 01 Oct 2022

Or, subject to the rules about excluded combinations, the discontinued modules M431, M822, M824, M826, M827, M828, M830, M841, M860, M861, MZX861, PMT600 and PMT601.

1 Only under exceptional circumstances may you study 150 credits at intermediate level, i.e. without first studying an entry-level module.
2If you choose Analytic number theory II (M829), you must take Analytic number theory I (M823) first.

30 credits from:
Module Credits
• Dissertation in mathematics (M840) 30
Next start: 01 Oct 2022

You should note that the University's unique study rule applies to this qualification. This means that you must include at least 60 credits from OU modules that have not been counted in any other OU qualification that has previously been awarded to you.

Entry requirements

Entry requirements
You should normally have a minimum of either:
• a 2:2 honours degree in mathematics or
• a 2:1 honours degree in a subject with a high mathematical content.

If you don't have such a qualification, your application will still be considered, but you may be asked to complete an entry test. Non-graduates will not normally be admitted.

Whatever your background, you should assess your suitability by completing our diagnostic quiz.

If you're new to postgraduate study in mathematics, start with a single module: either the applied mathematics module Calculus of variations and advanced calculus (M820) or the pure mathematics module Analytic number theory I (M823).


180 credits


Minimum 2 years.

How long it takes
• Most students complete this qualification in six years, at the rate of one module per year.
• The minimum time you may complete this qualification in is two years.
• There's no time limit for completing this qualification, but we can't guarantee the same selection of modules will continue to be available.
• Some modules start only once every two years.

Career relevance
Mathematics postgraduates can be found throughout industry, business and commerce, in the public and private sectors. Employers value the intellectual rigour and reasoning skills that mathematics students can acquire, their familiarity with numerical and symbolic thinking and the analytic approach to problem-solving which is their hallmark.

There are a variety of reasons for studying mathematics at postgraduate level. You may want a postgraduate qualification in order to distinguish yourself from an increasingly large graduate population. You may find that your undergraduate mathematical knowledge is becoming insufficient for your career requirements, especially if you are hoping to specialise in one of the more mathematical areas, which are becoming more sought after by employers. Or you may want to move on to a PhD in Mathematics. The extent of opportunities is vast and mathematics postgraduates are equipped with skills and knowledge required for jobs in fields such as finance, education, engineering, science and business, as well as mathematics and mathematical science research.
