About the CSS
The CSS (Central Superior Services) Competitive Examination is a rigorous federal level test administered by the Federal Public Service Commission (FPSC) to select candidates for prestigious civil service roles across Pakistan. The exam’s rules and regulations, covering age limits, eligibility, subjects, and quotas, are detailed in the official CSS Rules section on the FPSC’s website.
The CSS Exam Rules, issued by FPSC Pakistan, outline eligibility criteria, age limits (21–30 years), and a maximum of three attempts for candidates. The exam includes written tests, a medical exam, a psychological assessment, and an interview. Rules also define quotas, disqualification grounds, and subject selection for a fair recruitment process
Notable Paper Trends
