Maths for GCSE 9-1 Science 400 questions

Many good GCSE science students lose marks because they are worried by the maths but this 400 question multichoice quiz - see video - covering 30 theory and core practical topics across Chemistry, Physics and Biology - will help and features precisely the maths competencies I identified from extensive research into past papers.
Maths for Science covers obvious requirements like mean, interpreting graphs, rounding, percentage change and probability; but also extends for example to use of formula triangles and rearranging formulae, use of control, dependent and independent variables in experiments, chromosome counts, atomic mass and number, units of measure, isotope decay, carbon dioxide concentration and bond energy calculations. In fact anything that involves a number!
When you enter an answer by clicking, entering a,b,c or a number you get an immediate correct/try again colour coded answer. There is a reset button to start again. You can add questions with just a modicum of Excel skills.
