1. Exam Pattern & Selection Process

The UPSC Civil Services Examination is a multi-stage process designed to select the most capable individuals for various All India Services and Central Services. It comprises three distinct tiers:

1. Preliminary Examination (Prelims): This is the first screening stage, consisting of two objective-type papers (General Studies Paper I and CSAT Paper II). Marks obtained in Prelims are solely for qualification to the Mains examination and are not counted in the final merit list.
2. Main Examination (Mains): This stage consists of nine descriptive-type papers. The marks obtained in Mains, along with the Interview, determine the final ranking.
3. Personality Test (Interview): Candidates who qualify the Mains examination are called for an interview, which assesses their mental aptitude, critical thinking, and suitability for a career in public service.

Here's a detailed breakdown of the Preliminary Examination pattern:
