General Science — SSC GD Study Notes

Overview

General Science forms a critical pillar of the GK section in SSC GD, typically contributing 15–20 questions from Physics, Chemistry and Biology combined. This topic tests fundamental concepts at the matriculation level — the kind of science you encounter in daily life and read about in newspapers. Success here doesn't require deep theoretical knowledge but demands clarity on basic principles, definitions and real-world applications.

Questions are direct and factual: "Which vitamin deficiency causes scurvy?", "What is the SI unit of force?", or "Which gas is released during photosynthesis?" The exam rarely asks derivations or calculations but frequently tests your ability to connect concepts to everyday phenomena — why iron rusts, how vaccines work, or what causes tides. Students who revise NCERT Class 6–10 science textbooks thoroughly and stay updated on science-related current affairs (ISRO missions, Nobel prizes in science, new discoveries) score consistently well in this section.
