Essays and descriptive writing play a crucial role in the UPSC exam, particularly in the Mains, where the essay paper assesses candidates' writing proficiency, coherence of thought, and ability to structure arguments. Well-crafted essays demonstrate analytical thinking and depth of understanding about various issues. In descriptive papers, clarity and conciseness are emphasized, as candidates must articulate complex ideas succinctly. Mastery of these skills not only aids in exceptional performance in the written exams but also reflects a candidate's capability to communicate effectively in real-world administrative roles.
