How to Prepare
Focus on speed - Tier 1 gives about 36 seconds per question
You must handle 100 questions in 60 minutes. Attempt Reasoning first (fastest), then English, then GK, and leave calculation-heavy Quant questions for the end. Skipping smartly beats attempting everything.
Make English your Tier 2 weapon
Tier 2 English is worth 120 marks - the biggest single section. Master grammar rules, comprehension, and vocabulary, and read an English newspaper for 30 minutes daily.
Build GK from standard sources only
Use one standard static GK book plus the last 6 months of current affairs summaries. CHSL GK is roughly 60% static and 40% current affairs - do not drown in too many sources.
Start typing practice early for PA/SA/DEO/LDC roles
The Skill/Typing Test is qualifying but eliminates unprepared candidates: DEO needs 8,000 key depressions per hour; LDC/PA/SA need 35 WPM in English or 30 WPM in Hindi. Practise 20 minutes daily from month one.
Take weekly timed mock tests and analyse errors
Simulate the 60-minute Tier 1 format weekly, track accuracy per section, and revisit weak chapters. Practise free SSC CHSL mock tests and sectional quizzes on PrepClever to know exactly where you stand before exam day.
