Created by Maths teachers, Arc Maths is an award-winning app that helps you remember the crucial skills you need to succeed at Maths. It covers all the maths taught between the ages of 11-16 (including all GCSE topics). PERSONALISED LEARNING - Arc Maths’ clever AI works out what topics you need to practise, so there is no wasting time deciding what to work on. Thanks to new research into how memory works, the AI will choose questions designed to make you improve as quickly as possible. - Our introductory test will find a good starting level for you, but don’t worry if it isn’t perfect... the more questions you answer, the more our AI learns where your strengths and weaknesses lie. - Your path through the topics will be unique and tailored to you. The levels mark your progression through to total GCSE mastery! HANDWRITTEN ANSWERS - Thanks to some brilliant handwriting recognition, answering the questions couldn’t be easier! Simply use a fingertip and the app will interpret it – square roots, fractions, algebra, and more. - The experience is much more engaging thanks to a wide variety of question types. - Answering questions similar in style to an exam will raise your confidence and make you feel more prepared (rather than simply multiple choice.) TRACK YOUR PROGRESS - Your level will show how far through the GCSE content you are... completing level 10 means you should feel very confident on all GCSE topics. - Watch your XP increase with each correct answer, and your streak with each day you complete a session. - A session only takes 10 minutes so it can fit into your busy day. Switch on the notifications to remind yourself to do it daily and build a habit. - More details about your progress and topics answered can be found on our tutor portal.
