The What Is section is an exam encyclopedia — clear, comprehensive explainers of the important terms, concepts, institutions, laws, schemes, treaties and policies that appear in current affairs and competitive exams. Each entry gives a simple definition, key features, how it works, exam focus and quick revision points, so you can understand a topic in depth, not just memorise it.
Whenever you meet an unfamiliar term in current affairs — say repo rate, the Monetary Policy Committee or a new government scheme — the What Is section explains it fully: what it is, who runs it, how it works, why it matters and what exams ask about it. It turns one-off news mentions into durable, well-understood concepts.
Use these explainers to build your static foundation alongside daily current affairs. When an article mentions a concept you're unsure about, open its What Is entry, read the definition and exam-focus sections, and revise with the quick-revision points and FAQs. Related terms are linked so you can build a connected understanding of a topic.
It covers important terms, concepts, institutions, laws, schemes, treaties, indices and policies across polity, economy, science, environment, international relations, history, geography, social issues and defence.
Current affairs articles cover what happened; What Is explainers cover the underlying concept in depth — definition, mechanism, significance and exam relevance — so you understand the topic fully.
It is useful for UPSC, SSC, Banking, Railway and Defence aspirants who need to understand exam concepts clearly and quickly.
