An online version of CS50 will again be offered through the University of Oxford, starting September 14, 2026! Students in the course will meet weekly online with an Oxford tutor, Dr Nicholas Day, and, upon successful completion, will be eligible for a University of Oxford digital certificate.

If you or someone you know might like to take the course, apply at https://cs50.uk. Or send them https://youtu.be/R03gZT5H3Bk!

Dr Nicholas (Nick) Day is a Departmental Lecturer in Lifelong Learning for Data Science and Computing at OUDCE. He has taught at the department since 2016 on a range of programming, software engineering, artificial intelligence and data science courses. He completed his PhD in Computer Science Education (CSEd) in 2020 and now applies his pedagogical research to the development of courses and contributes to the department’s AI Steering Group. He is also a Senior Fellow of the Higher Education Academy (SFHEA), an AdvanceHE certified External Examiner, and a Professional Member of the British Computing Society (MBCS).
