Human Physiology: SSC CGL Biology
Human Physiology has 25 questions in the SSC CGL Tier I bank: 13 from the 2023 shifts, seven from the 2024 shifts and five from the 2025 shifts. Ten are on food and vitamins and the rest on the body's systems, from digestion to antibodies. Each page gives the pairs SSC asks, with the decoy it uses.
The handout has every subtopic, worked example, formula and trap with answers shown. The formula sheet is the chapter’s formulas and traps alone, on one page.
