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 Cambridge International’s, so check the current specification when a mark depends on one. The 9700 route map lists every heading, with the lessons that teach it.
