OOMC

Oxford Online Maths Club

Welcome to the club!

The Oxford Online Maths Club is a weekly livestream from the University of Oxford. It’s free, interactive, casual, and relaxed, and the livestreams are recorded so that you can watch back afterwards if you can't make it to the live broadcast on Thursday afternoons. Our regular host is Dr James Munro, and we often have current Oxford students answering questions in chat and appearing on the livestream to talk about maths.

The club is mostly aimed at people about to apply to university or about to start a Maths course, but everyone's welcome and there's no registration needed. Whether you’re the only person you know who’s interested in mathematics, or if you’re an entire sixth-form maths club looking for more maths content, we’re here for you.

Season 8

Season 8 runs for seven episodes through April and May 2024.

On 16 May and 23 May, we're excited to announce a Computer Science takeover of the Oxford Online Maths Club; our friends at Computer Science will present two episodes of the club on topics relevant to anyone interested in Mathematics and/or Computer Science.

Next Livestream

The Oxford Online Maths Club is live at 17:00 (UK time) each Thursday. The links below take you to the livestream and to the live chat feature.

The STEP support programme is a great set of maths resources, even if you're not going to take the STEP exams. Start here and then work through these; if they're too easy for you, then try these or eventually these. Dr Stephen Siklos's book Advanced Problems in Mathematics: Preparing for University is great, and free.

NRICH has lots of maths problems, investigations, games, and activities.

The Maths department at Oxford has written practice problems and material to help with bridging the gap, which some colleges send out to students to look at over the summer before starting the Oxford maths degree. The Bridging the Gap material has been expanded into the book "Towards Higher Mathematics: A Companion" by Dr Richard Earl.

The maths departmental prospectus has more information about the Oxford maths and joint honours degrees.

Full details of the courses currently offered as part of the Maths degree are available here. Please note that the courses offered may change year-on-year, and course details may change. Links to courses in specific years of the Maths degree;

Note that the courses are sorted by term (Michaelmas, Hilary, and Trinity are Oxford's names for the three terms).
