## The contemporary approach to raising GCSE maths grades by enabling short bursts of study on the student’s own smart phone.

The app allows students to revise on any mobile device, answering questions on each topic and seeing their accuracy level as they proceed. Students are first asked to choose whether they are taking the Higher or Foundation paper and the content is then adapted accordingly.

Key Topics: Number (Calculator and Non – Calculator)

Understanding numbers: decimals, fractions & percentages, recurring decimals, odd numbers, powers & roots, positive & negative numbers, factors & primes, product of primes; LCM & HCF, upper & lower bounds; mixed numbers, reciprocals & simplifying fractions; value, conversions & ratios; determining significant figures; calculating distance, speed & time; rounding & estimating; inverse & direct proportion, calculating percentage increases & decreases, compound interest, profit & loss; standard form; rationalisation & surds

Data Handling (Calculator and Non – Calculator)

Collecting, recording & representing data, arranging & analysing data; cumulative frequency tables & curves, histograms, scatter diagrams, space diagrams, tree diagrams, frequency diagrams, pictograms, composite bar charts, stem & leaf diagrams, plot boxes & pie charts; determining the mode, median & mean; grouped frequency calculations; averages & range; using probability; combined events, expectation & two way tables, surveys & data analysis, correlations & variables
