The Preliminary Examination in the UPSC selection process usually carries a weightage of about 25% of the total marks. Although it serves as a qualifying round, it is critical in determining which candidates advance to the Mains. This stage tests candidates' general awareness, comprehension, and analytical skills through objective-type questions. Acceptance into the subsequent rounds hinges on performing well enough to surpass cut-off marks, underscoring the importance of serious preparation for this initial phase.
