General Knowledge and General Sciences can often feel like an ocean to students. Unlike Mathematics or Reasoning, where rules apply universally, GK requires massive memorization. For Sainik Schools (AISSEE) and Rashtriya Military Schools (RMS), this section is entirely objective and acts as a major rank-decider because it takes seconds to answer each question, saving crucial time for Math.
1. General Science (The Heaviest Weightage for Class IX)
For Class VI, science is mixed with general environmental studies. For Class IX, it is a standalone 50-mark section that demands deep conceptual clarity.
Physics:
- Force and Pressure: Types of forces (contact and non-contact), atmospheric pressure.
- Friction: Causes, advantages, disadvantages, and methods of reducing friction.
- Sound: Production, propagation, amplitude, frequency, and the human ear.
- Light: Reflection (laws of reflection, regular vs. diffused), multiple reflections, mirrors, lenses, and the human eye structure.
- Electricity & Magnetism: Chemical effects of electric current, electroplating, and properties of magnets.
- The Universe: Stars, the solar system, phases of the moon, and artificial satellites.
Chemistry:
- Synthetic Fibers and Plastics: Types (nylon, rayon, polyester), characteristics, and environmental impact.
- Metals and Non-Metals: Physical properties (malleability, ductility) and chemical reactions (with oxygen, water, acids).
- Coal and Petroleum: Fossil fuels, refining of petroleum, and natural gas.
- Combustion and Flame: Types of combustion, structure of a flame, and fuel efficiency (calorific value).
Biology & Environment:
- Cell Structure and Functions: Plant cell vs. animal cell, organelles (nucleus, mitochondria, chloroplasts).
- Microorganisms: Friend and foe (bacteria, fungi, protozoa, viruses), nitrogen cycle, and food preservation.
- Human Body & Health: Digestive, respiratory, and circulatory systems. Vitamins, minerals, and deficiency diseases (e.g., Scurvy, Rickets, Beriberi).
- Agriculture: Crop production and management, traditional vs. modern irrigation, fertilizers, and manures.
- Conservation: Deforestation, endemic species, wildlife sanctuaries, national parks, and biosphere reserves.
2. History & Indian Heritage
The focus here is heavily skewed toward Modern India and the freedom struggle, with a light touch on ancient and medieval periods.
- Ancient India: Indus Valley Civilization, Vedic period, Jainism, Buddhism, and the Mauryan/Gupta Empires.
- Medieval India: The Delhi Sultanate, the Mughal Empire (key rulers, monuments), and the Marathas.
- Modern India (High Yield): The Revolt of 1857 (causes, key centers, and leaders).
- Establishment of the Indian National Congress.
- The Gandhian Era: Non-Cooperation Movement, Civil Disobedience, Quit India Movement.
- Key social reformers (Raja Ram Mohan Roy, Swami Vivekananda, Dayanand Saraswati).
3. Geography
Geography questions are direct and factual. Map reading skills are essential here.
- Physical Geography: Interior of the Earth (crust, mantle, core), rocks and minerals, earthquakes, and volcanoes.
- Mathematical Geography: Latitudes, longitudes, standard time, rotation, and revolution of the Earth.
- Indian Geography: Physical features: The Himalayas, Northern Plains, Peninsular Plateau, Coastal Plains, and Islands.
- River systems: Himalayan rivers (Ganga, Brahmaputra, Indus) vs. Peninsular rivers (Narmada, Godavari, Krishna).
- Climate, natural vegetation, and major soil types in India.
- World Geography: Continents, oceans, major mountain ranges (Andes, Alps, Rockies), and major deserts.
4. Civics & Indian Polity
This section tests a student’s basic understanding of how the country is run.
- The Indian Constitution: Framing of the constitution, Preamble, Fundamental Rights, and Fundamental Duties.
- Government Structure: Union Government: The President, Prime Minister, Lok Sabha, and Rajya Sabha.
- State Government: Governor, Chief Minister, Vidhan Sabha.
- Local Self-Government: Panchayati Raj system and Municipalities.
- Judiciary: The Supreme Court and High Courts.
- International Bodies: The United Nations (organs and specialized agencies like WHO, UNESCO, UNICEF).
5. Static GK & Defense (The Military School Differentiator)
Since these students are preparing for military academies, this section is non-negotiable and heavily tested.
- Indian Armed Forces: Commands of the Army, Navy, and Air Force. Equivalent ranks across the three services. Major weapons, missiles (Agni, Prithvi), and recent defense acquisitions.
- Firsts and Superlatives: First in India/World (male and female). Largest, longest, highest, and smallest in India and the world (e.g., longest dam, highest peak).
- National Symbols: National flag, anthem, song, emblem, bird, and animal.
- Art and Culture: Classical and folk dances of different states, major festivals, and classical music instruments.
- Sports: Number of players in different games, sports terminologies, major trophies/cups (e.g., Thomas Cup, Durand Cup), and recent Olympic/Commonwealth achievements.
- Books and Authors: Historical books and famous modern literature.
- Important Days: National and international days (e.g., Army Day, Earth Day, UN Day).
