• Straight lines, parallel and perpendicular lines

    Master all the different forms of the equation of a straight line, and be confident using parallel and perpendicular lines

  • Differentiation + tangents and normals to curves

    Understand how to describe the gradients of curves in general and be confident finding the equations of tangents and normals to these curves.

  • Solve challenging problems

    After solving a mixture of introductory GCSE and A-level style problems and harder maths challenge style problems, all with video solutions, you'll have really mastered the topics.

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.

Get me ready!

Master the hardest parts of GCSE and IGCSE and get ahead with A-level maths topics.

In this course you will learn how to describe the equation of a straight line in a number of useful ways, and to fully understand parallel and perpendicular lines. You will go on to learn how to extent the definition of gradient to more general curves and will be able to differentiate polynomials and other power functions as well as being able to compute the equations of tangents and normals.

  • Suitable for students at the end of GCSE/IGCSE or the start of A-level (usually ages 15-17).

  • Learn by doing - as well as video introductions, each of the 5 chapters is organised around a contains an original downloadable worksheet.

  • Each worksheet has a range of easier and harder questions as well as some 'starred' questions to stretch the strongest students.

  • Every question in each worksheet has a fully explained video solution.

  • Free preview sections available after logging in (no payment details needed).

  • Available 24/7, go at your own pace. No ads, no distractions.
