How this analysis is made

Every question in each paper is tagged with its topic, format and marks as printed. The figures above are counts over those questions: a topic's share of marks, the share of papers that include it, and so on. Topic names come from the papers and their answer keys, so similar topics can appear under slightly different names. Only aggregate figures are shown here; the questions themselves are practised inside PaperLah.
