The CSAT (Civil Services Aptitude Test) is significant as it serves as a qualifying exam for the UPSC Prelims. Candidates must achieve a minimum score to proceed to the General Studies paper. The test evaluates mathematical skills, comprehension, and logical reasoning. Though it is not heavily weighted in terms of actual scores impacting rankings, failing to pass can disqualify a candidate from the entire examination process. Thus, a solid preparation strategy for CSAT is essential to ensure smooth progress in the overall UPSC journey. Candidates often focus on practicing quantitative aptitude and comprehension exercises to enhance their performance.
