Kevin Olding - Mathsaurus
Whether you're preparing for a maths challenge, or aiming for top grades at GCSE or A-Level or have a student taking 11+ exams or are teaching online, you’ve come to the right place. A lot of my content is right here on YouTube, but a lot more is available at the online courses website too at https://courses.mathsaurus.com/ - there you'll find loads of free online courses as well as details of my paid teaching. There's also a website at mathsaurus.com with lots of past papers and grade boundaries.
About me: I studied maths at Oxford University and later created this channel whilst teaching maths at two of the top private schools in London. Since leaving full time teaching I have completed a PhD in Probability and now make content for this channel and the online courses full time!
