This 26-lesson course includes all the material you need for the ‘Ratio, Proportion and Rates of Change’ section of the brand new Maths (9-1) GCSE qualification. Each lecture includes slides and step-by-step examples for every topic, along with worked solutions for practice exam questions.


Throughout the course, I will talk you through the basics of every concept and section, before moving on to practice exam questions. This makes this course suitable for all abilities, whether you are learning GCSE Maths from scratch, or in need of revision leading up to exams.


Course Structure


The course follows the standard Maths GCSE structure (as used by Edexcel, AQA and OCR), meaning it is easy to follow and perfect to use alongside any other learning or revision you may be doing. The course is split up in to the following sections:


·      Ratio

·      Direct and Inverse Proportion

·      Percentages

·      Compound Growth and Decay

·      Unit Conversions

·      Speed, Density and Pressure


We will also take a quick look at the recent changes to GCSE Maths in the UK, and how it has affected the grading system and exam structure. If you follow this course, you will gain a solid understanding of all of the above topics, whilst greatly improving your ability to answer questions on exam day.
