GS Paper 3 is the data-heavy paper — economy, agriculture, science and tech, security, environment and disaster management — where the right number or scheme name lifts an answer. This is the largest volume in the set: 154 exam-realistic questions, each with a complete model answer.

Every question comes with the intro–body–conclusion outline a high-scoring answer follows, the budget figures, committees, schemes, technologies and reports examiners look for, concrete examples and case studies, and a model answer written within the word limit — with sources to verify and read more.

The 154 questions are organised across the economy, agriculture, science and technology, internal security, environment, ecology and biodiversity, climate change, sustainable development and disaster management — the most complete coverage of any paper in this series.

Work it as a timed drill book: attempt each answer cold, then grade against the outline, key points and model answer. The volume of questions is deliberate — enough to practise daily for months and still meet fresh material.

This is a 285-page PDF compiling 154 practice questions, readable on any device or printable for annotation — part of the Anantam IAS UPSC Mains Practice Questions series. Each question links back to its live version at anantamias.com/mains-practice-questions/.
