Reading too many books for one subject β pick ONE source, master it.
Skipping NCERTs β they have 60% of static syllabus base.
No revision plan β revise weekly, monthly, 30 days before exam.
No answer writing practice β Mains is 1750 marks of writing. You can't wing it.
Optional choice based on others' selection β choose what you can sustain interest in for 6+ months.
Burnout in month 4 β schedule rest, don't binge.
Newspaper reading without notes β reading without retention.
Random YouTube binging β picks 2-3 quality channels (Mrunal Patel, ForumIAS, Vision IAS), stop scrolling.
Not joining a peer group β accountability + discussion 10x retention.
Stage 5: Mental Strategy
Realistic timeline: 12-15 months of focused work.
2 attempts on average for selection (most toppers cleared on attempt 2-4).
Plan B: In parallel apply for SSC, Banks, State PSC. Selection in any of these is success.
Health: 7-8 hrs sleep. Daily 30 min walk. No skipping meals.
Family + finance: Realistic conversation about funding 12-18 months of preparation. Side income (tutoring, freelance) helps.
Special Categories
Working professional β possible but harder. 4 hrs/day for 18-24 months.
Recent graduate β 12-15 months optimal.
Engineering background β strong in CSAT + analysis. Weak in history, art-culture β focus there.
Humanities background β strong base. Focus on quant + science.
