Flashcards for SQA Higher Applications of Mathematics (C844 76), split into the specification's four skill areas (mathematical modelling, statistics and probability, finance, and planning and decision making) and then by skill in its order. Worked examples use their own figures throughout, never a past paper's.

Adding it gives you your own copy, with every subdeck below. Each card then comes back just before you would forget it, and every one you get right or wrong counts towards your mastery of its topic. You can delete or suspend the parts you are not studying once it is yours.
