Yes, you can often study a Master’s in Data Science, Artificial Intelligence or Cybersecurity in the UK without a Computer Science degree, if you have a numerate or technical background or a conversion course. Entry rules vary by course, and some cybersecurity and advanced computing courses need ATAS clearance for Nigerian students.
What is a conversion Master’s?
A conversion Master’s is designed for graduates from another subject who want to change into computing or data. It usually starts with foundations such as programming, statistics and databases, then moves to advanced topics. Some are labelled “conversion”, while others are regular MSc courses that accept non-computing graduates.
Who can apply from a non-CS background?
- Graduates in engineering, mathematics, physics, statistics, economics, accounting or other quantitative subjects.
- Graduates in business, science or social science with programming or analytics experience.
- Professionals who have worked with data, software, networks or IT systems.
Some universities accept applicants from any subject but ask for evidence of maths or programming. Others require a minimum number of mathematics or programming modules in your degree.
Course options at a glance
| Field | What you study | What to check |
|---|---|---|
| Data Science | Statistics, machine learning, data analysis, visualisation, programming | Maths and programming prerequisites |
| Artificial Intelligence | Machine learning, neural networks, language and vision systems | Strong maths, often some programming |
| Cybersecurity | Network security, cryptography, secure systems, ethical hacking | ATAS requirement and technical background |
| Computer Science conversion | Programming, algorithms, software engineering | Designed for non-CS degrees; check structure and length |
Do you need ATAS?
Some computing and security courses require an ATAS certificate for non-UK students. The requirement depends on the course subject code, so ask the university. See our ATAS guide for Nigerian students.
How to prepare if you have no CS degree
- Learn the basics. Study Python, SQL and introductory statistics with free or low-cost online courses.
- Build small projects. A short analysis project or a simple application shows motivation.
- Collect evidence. Keep certificates, project links and a CV that highlights relevant skills.
- Write a clear statement. Explain why you are changing fields and what you will do with the Master’s. See how to write a statement of purpose.
- Check grades and English. See UK entry requirements for Nigerian students.
Computer Science Master’s vs conversion course
If you already have a CS degree, see our top UK universities for Computer Science. If you do not, choose a course that is clearly open to non-CS graduates, and look for modules that start from the basics.
Costs, funding and work after study
Technology courses can have high international fees. Compare the total cost with the career plan in is a UK Master’s worth it? and look at scholarships for Nigerian students. After the course, the Graduate Route may allow you to stay and work for a limited period, subject to the current rules.
Frequently asked questions
Can I study Data Science in the UK without a computer science degree?
Often yes, particularly with a quantitative degree or relevant experience. Check each course’s entry requirements.
Is a conversion Master’s accepted for jobs in tech?
Employers look at skills and projects as well as the degree. A portfolio helps.
Does cybersecurity need ATAS?
Some courses do. Confirm with the university before you apply for a visa.
Is a conversion Master’s longer than a standard MSc?
Some are longer or include a foundation stage. Check duration and fees.
