Aspirants can create an effective revision plan for the UPSC syllabus by first conducting a detailed syllabus analysis to understand the weightage of subjects. They should then allocate time to each topic based on their strength and weakness, using the SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound). Incorporating regular mock tests is vital to gauge progress and identify areas needing improvement. Additionally, setting daily, weekly, and monthly goals can help maintain focus and motivation. A consistent review of current affairs and effective note-taking techniques will further enhance retention.
