CSS Physics Syllabus — FPSC PDF Download

The CSS physics syllabus carries 200 marks and is one of the Group II optional subjects which includes Geology, Chemistry, Applied Mathematics, Pure Mathematics, and Statistics. under the Central Superior Services examination rules set by FPSC. Group II requires candidates to select subjects totaling 200 marks — Physics alone fulfils this requirement as a single 200-mark paper. FPSC sets the CSS physics syllabus to cover mechanics, thermodynamics, electromagnetism, optics, waves, modern physics, and quantum mechanics — drawing from standard undergraduate physics curriculum. The Federal Public Service Commission publishes the official topic breakdown on fpsc. Physics graduates and engineering candidates consistently choose this optional subject because the FPSC syllabus maps directly onto BSc Physics coursework, making it one of the most preparation-efficient optional subjects in Group II.
