UPSC Mains Examination

The UPSC Civil Services Mains Examination (Mains) is the second stage of the Civil Services Examination (CSE), conducted by the Union Public Service Commission (UPSC). Unlike the Preliminary Exam (Prelims), which is an objective-type screening test, the Mains is a descriptive written exam. It is designed to assess a candidate’s depth of knowledge, analytical abilities, and writing skills across a wide range of topics.

The Mains Examination is crucial, as the marks obtained in this stage directly contribute to the final merit list, along with the interview stage. Let’s explore the structure, syllabus, and preparation strategies for the UPSC Mains.
