What Is General Knowledge and Why Does It Matter?
General knowledge (GK) is the information accumulated over time through education, media, and everyday experience. Unlike specialized expertise, GK spans every field — from science and history to pop culture and geography. Strong GK helps you in job interviews, competitive exams, social conversations, and of course, quiz nights.
