Static GK decides most of the General Awareness score in SSC exams. The CGL, CHSL and CPO notices describe it in almost the same words: questions on India and its neighbouring countries in History, Culture, Geography, the Economic Scene, General Policy and Scientific Research, and on everyday observation in its scientific aspect. The GD notice adds Sports, General Polity and the Indian Constitution, and the MTS notice lists Social Studies, General Science and Environmental Studies up to the 10th Standard. This page brings together GK24's GK notes and practice questions tagged for all five SSC exams. The notes follow a subject-wise syllabus, one topic per note in English and Hindi: Indian Polity, Indian History, Geography, Indian Economy, General Science, Environment and Ecology, Art and Culture, Computer, Sports, Awards and Honours, Books and Authors, Days and Dates, and Static GK. Each note is written as short facts and tables so that a topic can be revised in one sitting, and each ends with multiple-choice questions and explanations. The level is what changes between exams: read MTS and GD topics at Class 10 depth, CHSL at Class 12 depth, and CGL and CPO at graduate depth, where questions ask for the article number or the year rather than the broad idea. Start with Polity, History and Geography, which fill the most questions in past papers in GK24's reading, then move to the Economy and Science. After each note, solve its questions here and your exam's previous-year questions on its own page.

Read the full explanation →Two metallic wires A and B are made using copper. The radius of wire A is r while its length is l. A dc voltage V is applied across the wire A, causing power dissipation, P. The radius of wire B is 2r and its length is 2l and the same dc voltage V is applied across it causing power dissipation P₁. Which one of the following is the correct relationship between P and P₁?
Wire B has half the resistance of wire A, and at the same voltage power is V²/R, so B dissipates twice the power: P₁ = 2P, which means P = P₁/2.

Pressure is force divided by the area in contact: the weight is 2 kg × 10 m/s² = 20 N and the face touching the table is 0.30 m × 0.10 m = 0.03 m², so the pressure is 20 ÷ 0.03 ≈ 666.6 N/m².
Read the full explanation →A current of 0.6 A is drawn by an electric bulb for 10 minutes. Which one of the following is the amount of electric charge that flows through the circuit?
Electric charge equals current multiplied by time, Q = I × t, with time in seconds: 0.6 A × 600 s = 360 coulombs.
