Master the hardest parts of GCSE and IGCSE and get ahead with Alevel 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 Alevel (usually ages 1517).

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).

FAQ

Is this course suitable for a student who has already taken IGCSE Further Maths or OCR FSMQ Add Maths?
No  much of the content of this course is also covered in these qualifications. The course has been designed to give most benefit to a student who has just taken GCSE or IGCSE maths and is preparing for Alevel or any course that follows directly on from GCSE. It would be a great course for someone about to take one of these qualifications though, so long as they have mostly covered GCSE/GCSE maths already.

How long will my enrolment last?
Access to the course lasts for one year or two years depending on the option chosen.
