General Science — SSC CGL Study Notes

Overview

General Science forms a critical component of the General Awareness section in SSC CGL Tier 1, typically contributing 10–15 questions out of 25. This section tests fundamental concepts from Physics, Chemistry, and Biology at the Class 10 level. The questions are designed to assess your understanding of basic scientific principles, everyday applications, and factual knowledge rather than complex problem-solving.

Success in General Science requires clarity on core concepts across all three branches. Questions often relate to practical applications—why the sky is blue, how vaccines work, what causes rusting—making this section accessible through real-world connections. Unlike other GA topics that demand extensive memorization, General Science rewards conceptual understanding combined with selective fact retention. Students should focus on fundamental laws, common phenomena, human body systems, and everyday chemistry rather than attempting to memorize entire textbooks.
