What is the difference between the Preliminary and Mains Examination in UPSC?
The Preliminary Examination consists of two objective-type papers that test general knowledge and comprehension. It serves as a screening test, determining which candidates may proceed to the Mains. In contrast, the Mains Examination features descriptive-type papers, assessing candidates on a wide range of topics, including optional subjects and essay writing. The Mains delve deeper into subjects and evaluate analytical, critical thinking, and presentation skills, making it a more intricate part of the selection process.
