From Pocket Revision Ltd:
Fun, colourful and interactive GCSE maths revision apps providing thousands of examples, clues and easy-to-remember revision notes. Passing your maths exam starts here!Why did we create these apps?Because we know how it feels to read through big, boring, heavy maths textbooks. And we didn't like it either!What's so good about them?Unlike textbooks and some other maths apps out there, most of the examples in our apps are randomly generated and can be shuffled an unlimited number of times. This means that you won't be able to memorise answers, and that you'll actually learn how to do the working out properly! It also means that you'll be continuously tested.....So what makes them not boring?All of our apps are colourful and interactive. You're not just reading pages upon pages of numbers. You're actually looking at questions, revealing clues to help you out, and then (hopefully) working out the correct answer!
