Hi, I'm Kevin, your teacher for this course!
I studied maths at Oxford University and learnt to teach at some of the UK's most prestigious private schools. I'm also an experienced and highly sought after private tutor with a popular maths YouTube channel. I've created these Mathsaurus courses so you can learn to do maths like the very best on a fraction of the budget.
This course has been designed to replicate the experience of private tuition, with video hints and solutions as you work through the course that make it feel like you're in a real lesson.
I really enjoyed making this course and I hope that as well as learning a lot you're going to have fun along the way too. In the video introduction below I'll tell you more about the course. Then if you're ready to get started you can sign up for the free preview or the full course or learn more about it further down the page.
