Geophysical Phenomena — PYQ Trend Intelligence

What the data shows

In the mapped 2013–2026 GS 1 dataset, 16 questions connect to geophysical phenomena across 11 exam years. The highest observed count is 2 in 2026, 2017, 2016, 2014, 2013. 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 GS1. 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.

Questions by year

Answer-writing intelligence

Directives recorded for mapped questions include Explain, Analyze, Discuss, Differentiate, Examine. Compare how the demand changes across years: identify the directive, split the question into its components, and practise within the stated mark allocation.
