What Is GCE Introductory Microeconomics?

GCE Introductory Microeconomics is a foundational course commonly offered in international schools. It is part of the GCE AS-Level (Advanced Subsidiary Level) or IGCSE (International General Certificate of Secondary Education) Economics curriculum.

Microeconomics focuses on the behavior of individual economic units—such as consumers, firms, and industries—unlike macroeconomics, which examines the economy as a whole.
