Here is an example of a Mashup problem, requiring knowledge of circle theorems, ratios, and trigonometry:

The class QLAs (typically around 1 MB) can take data for up to 40 students while the cohort QLAs (typically around 5 MB) can take data for up to 300 students. The QLAs are otherwise identical. Because of the formulas in the spreadsheets, older computers may struggle to load or run the cohort QLAs, but should be fine with the class QLAs.
