GSA Syllabus CSS — General Science and Ability Download PDF

The GSA syllabus for CSS carries 100 marks. It is one of six compulsory papers set by FPSC — the Federal Public Service Commission — under the Central Superior Services examination rules. The General Science and Ability CSS syllabus covers everyday science, basic mathematical reasoning, and analytical ability drawn from the natural and physical sciences. Unlike Current Affairs or Pakistan Affairs, the CSS GSA syllabus does not change with the news cycle. Its topics are fixed, published on fpsc.gov.pk, and consistent across examination years. That makes it the most predictable of all six compulsory papers to prepare for.
