Static GK makes up most of the General Awareness syllabus of RRB JE, and General Science adds a larger block of its own. CEN 04/2026 lists Indian geography, the culture and history of India including the freedom struggle, Indian Polity and Constitution, the Indian Economy and environmental issues concerning India and the world. In CBT-1 these share 15 questions with current affairs, while General Science, which the CEN defines as Physics, Chemistry and Life Sciences up to the 10th Standard CBSE syllabus, has 30 questions of its own. CBT-2 repeats the General Awareness syllabus in 15 questions and adds 15 on Physics and Chemistry, 10 on Basics of Computers and Applications and 10 on Basics of Environment and Pollution Control. This page holds GK24's topic-wise GK notes for RRB JE: Polity, History, Geography, the Economy, Art and Culture, Environment and Ecology, General Science and Computer basics. Each note is a set of short facts and tables in English and Hindi that can be revised in one sitting. Read one topic, solve its quiz and previous-year questions, and return to it a week later. With 15 General Awareness questions spread over eight areas, breadth matters more than depth, while General Science rewards thorough revision of Class 10 concepts.
