Learning objectives and outcomes

Objective 1Know the core SI units and single-fact science answers by heart.
Objective 2Know India's key economic institutions and their roles.
Objective 3Recall the headquarters of major international organisations.
Outcome ATreat this chapter as a set of compact, memorisable facts rather than concepts to derive.
Subtopic 1

General science essentials

Science questions in this exam draw from basic physics, chemistry and biology — SI units, common constants, and single-fact biology questions.

Facts worth having automatic

SI unit of force — Newton  ·  SI unit of power — Watt
Speed of light — ≈ 3×10⁸ m/s  ·  Vitamin C — ascorbic acid
Insulin — produced by the pancreas  ·  Photosynthesis — occurs in chloroplasts

Most science questions in this exam are single-fact recall rather than calculation, so the payoff is in memorising a compact list rather than understanding derivations.

Memory trick — "Newton pushes, Watt powers"

Force (Newton) is about pushing or pulling; power (Watt) is about the rate of doing work — keeping the everyday meaning of each word in mind prevents mixing up which unit belongs to which quantity.

Easy
The SI unit of force is:
The SI unit of force is the Newton (N).
Moderate
Which organ in the human body produces insulin?
Insulin is produced by the pancreas, specifically by its beta cells.

Subtopic 2

Economy and banking

Economy questions focus on India's central bank, major regulatory bodies, and a handful of key international financial institutions.

Key institutions

RBI — established 1935, HQ Mumbai  ·  SEBI — regulates the securities market
IMF & World Bank — both HQ Washington, D.C.
GST — Goods and Services Tax  ·  GDP — Gross Domestic Product

The RBI issues all Indian currency notes except the ₹1 note, which is issued by the Ministry of Finance — a frequently tested exception to an otherwise simple rule.

✈ AAI ATC relevance — the RBI's founding year and headquarters, plus the IMF/World Bank headquarters, are asked almost every attempt
Memory trick — "Washington holds both the IMF and the World Bank"

Unlike most pairs of international organisations, the IMF and World Bank share the same headquarters city, Washington, D.C. — one fact covers both.

Easy
RBI headquarters is located in:
The Reserve Bank of India is headquartered in Mumbai.
Moderate
The headquarters of the IMF (International Monetary Fund) is located in:
The IMF is headquartered in Washington, D.C., USA, the same city as the World Bank.

International organisations and national symbols

This final cluster covers where major world bodies are headquartered, and India's officially designated national symbols — both compact, high-frequency topics.

Headquarters and symbols

UN — New York  ·  WHO — Geneva  ·  UNESCO — Paris
National bird — Peacock  ·  National animal — Bengal tiger

UN, WHO and UNESCO headquarters are three of the most repeated "where is it headquartered" facts across GK sections generally, not just for this exam.

Memory trick — "New York, Geneva, Paris — three cities, three bodies"

UN-New York, WHO-Geneva, UNESCO-Paris forms a short, distinct triplet that's easy to recite as a set, rather than memorising each headquarters in isolation.

Easy
The headquarters of the United Nations is located in:
The United Nations headquarters is located in New York, USA.
Moderate
The national animal of India is the:
The Bengal tiger is India's national animal.
