Random study usually happens when preparation is not guided by the syllabus or a clear plan. The easiest way to avoid this is to study the UPSC syllabus topic-by-topic and connect what you learn with Previous Year Questions.

Having a simple study plan for each phase of preparation helps you know what to focus on and what to ignore. Using structured self-learning tools to track coverage, revision, and practice can keep your preparation organised and consistent.
