Shape and Space topics cover everything from rectangles to vectors, Pythagoras’ Theorem and trigonometry. It includes the higher-tier topics like sine and cosine rule.
Probability topics range from basic probability through to conditional probability tree-diagrams. Statistics topics start with the median and go through cumulative frequency to histograms.
Number and Algebra topics start with fractions and go all the way to completing the square and solving simultaneous equations where one is quadratic.
The material is organized into 14 topics and each topic is split down into the important and difficult skills – 68 skills in all. There is a learning screen with quick and clear revision notes plus diagrams to explain the problem solving techniques. Then you can choose from three screens to progress further.
The Videos screen shows our selection of one or more videos for each skill from outstanding teachers around the world hosted on YouTube. These are a great way to get a more in-depth look at the skill.
The Questions screen has two practice questions for each skill to confirm your understanding. These are both numerical and multiple-choice. The app will mark them for you and tell you the correct answer if need be. You can do some working in colour on the Questions page.
Finally, there is a colour sketch-pad to let you do more extensive working on more difficult problems.
Although it is focused on the needs of English school students the same topics are studied all around the world and this will be useful to most students taking exams between ages 15 and 17.
