A topic is listed under every section its lesson teaches, so some appear more than once. The codes beside each one are the specification headings it covers in that section.
The sections and codes are Pearson Edexcel’s; check the current specification when a mark depends on it. The 8CH0/9CH0 route map lists every heading, with the lessons that teach it.
