What the data shows
In the mapped 2013–2026 GS 3 dataset, 40 questions connect to environment, conservation and climate across 14 exam years. The highest observed count is 5 in 2022, 2021, 2020. These counts describe historical coverage, not the probability of a future exam question.
Method: topic hierarchy adapted from the supplied GS1–GS4 topic-map PDFs (2013–2025); questions are linked using MainsBuddy metadata term matching, restricted to GS3. Overlapping themes may include the same question. 2026 questions are mapped as a separate extension beyond the PDFs. Cross-topic matches may occur; these are provisional classifications, not verified question-level PDF mappings.
