UPSC Prelims Revision Schedule (Next 90 Days): A Smart 3-Month Plan to Maximise Your Score

With just 90 days left for UPSC Prelims, revision - not new study; should be your top priority. The next three months can determine whether you clear the cut-off or fall short.

Why 90-Day Revision Is Crucial

• Prelims tests retention, not just knowledge
• Questions are increasingly conceptual
• Static + Current Affairs integration is key

The goal is simple: Revise → Test → Analyse → Improve → Repeat.

• Identify weak areas
