IB Diploma Programme (DP) – Group 3: Individuals & Societies

Complete Guide to Subjects, Assessment, Skills & Preparation Strategy. Group 3 subjects explore how individuals and societies interact, make decisions, use resources, and respond to change.

These courses develop critical thinking, analytical writing, data interpretation, and evaluation skills essential for university study in humanities, social sciences, business, law, and international relations.
