In the UPSC Preliminary exam, candidates can expect a range of question types, including general studies covering topics like history, geography, polity, and environment, as well as current affairs. Questions may be formatted as multiple-choice queries that assess both factual knowledge and the ability to apply concepts. Some questions may also require comprehension of graphs and data interpretation. Hence, a comprehensive understanding of the syllabus, coupled with regular practice through mock tests, is crucial for success.
