Part IV — General Knowledge: Geography, Economy & Science

Chapter 4: Physical/Economic Geography and General Science

4.1 Physical Geography of India

India spans diverse physical features: the Himalayan mountain range in the north, the Indo-Gangetic Plain, the Thar Desert (predominantly in Rajasthan), the Deccan Plateau, and coastal plains along the Western Ghats and Eastern Ghats. Major river systems include the Himalayan rivers (Ganga, Yamuna, Brahmaputra — perennial, glacier-fed) and Peninsular rivers (Godavari, Krishna, Kaveri — rain-fed).

4.2 Economic Geography and Sectors

India's economy is divided into the primary sector (agriculture, the largest employer), secondary sector (manufacturing/industry), and tertiary sector (services, the largest contributor to GDP). The Union Budget is typically presented on 1 February each year.

4.3 General Science: Physics and Chemistry Basics

Fundamental physics concepts tested include the states of matter, basic laws of motion, and simple machines. Chemistry basics cover the periodic table's structure and common compounds' properties.

4.4 General Science: Biology Basics

Photosynthesis is the process by which green plants convert light energy into chemical energy, using carbon dioxide and water, releasing oxygen as a byproduct. DNA (Deoxyribonucleic acid) carries genetic information in living organisms. The human body's major organ systems (circulatory, respiratory, digestive, nervous) are commonly tested at a basic conceptual level.

4.5 Inventions, Awards, and International Organisations

Common topics include major scientific inventions and their inventors, national and international awards (Bharat Ratna, Nobel Prize, Padma awards), and international organisations' headquarters (UN — New York, WHO — Geneva, IMF/World Bank — Washington D.C.).
