SSC CHSL Syllabus 2026 — Complete Tier I & Tier II Breakdown

SSC CHSL (Combined Higher Secondary Level) recruits for LDC, JSA and Data Entry Operator posts and is open to anyone who has passed Class 12 — no graduation required. This guide covers the complete Tier I and Tier II syllabus, the skill/typing test rules, and how the two tiers differ from SSC CGL.

The low eligibility bar is the defining feature of this exam and it cuts both ways. It means you can sit for CHSL while still in college, or straight after school, years before you would be eligible for CGL. It also means the applicant pool is enormous relative to the vacancy count, and cut-offs sit uncomfortably high for a Class 12 level paper. The questions are not hard; the margin for error is.

That single fact should shape your preparation. In an exam where the paper is easy and the competition is heavy, marks are lost to speed and silly errors far more often than to genuine ignorance. Accuracy discipline matters more here than in CGL, and the typing test — which decides nothing on merit but can disqualify you outright — deserves attention from week one rather than the fortnight before.

Tier II Syllabus (100 Questions · 200 Marks · 60 Min)

Tier II is where the actual merit is decided — Tier I is only a screening round. It's split into two sections with different subject weightage than Tier I.

Skill Test / Typing Test (Qualifying)

• Data Entry Operator (DEO) post: Data Entry Speed Test — 8,000 key depressions per hour
• LDC / Junior Secretariat Assistant (JSA): Typing Test — 35 words per minute in English OR 30 wpm in Hindi
• No marks are added to merit — this stage is purely qualifying, but missing the speed cutoff means disqualification

How to Prepare for SSC CHSL 2026

1. Since Tier I and Tier II share the same subjects, prepare topics once at Tier II depth — don't relearn twice
2. English carries the highest weight in Tier II (40 questions, 80 marks) — prioritize vocabulary and RC daily
3. Practice typing early if targeting LDC/JSA — 35 wpm needs weeks of daily practice, not last-minute cramming
4. Attempt 1 full-length Tier I mock weekly from Day 1 to build exam-day speed
5. Revise Current Affairs from the last 6 months — General Awareness is scored purely on recall

How CHSL Differs from SSC CGL

The two exams share a subject list, which leads a lot of candidates to assume they are the same paper at different difficulty levels. They are not, and the differences change how you should prepare.

The practical takeaway is that CHSL Maths is shallower but not easier to score in, because everyone else finds it shallow too. Where CGL rewards depth in advanced maths, CHSL rewards speed and accuracy in arithmetic. A candidate preparing for both should build CGL-level maths and simply run CHSL papers faster — the reverse does not work.

Section-by-Section Strategy for Tier I

Sixty minutes, a hundred questions, four sections of equal weight. Unlike the banking exams there are no sectional time limits, so you are free to allocate as you like — and that freedom is what most candidates mismanage.

General Intelligence — go first

The fastest section in the paper. Analogy, series, coding-decoding, blood relations and Venn diagrams are recognition questions, and at CHSL level they are noticeably gentler than CGL. Target all 25 in eleven or twelve minutes with 23 correct. Non-verbal reasoning — mirror images, paper folding, embedded figures — is the only part that reliably slows people down, and a week of focused practice largely fixes it.

General Awareness — seven minutes, twenty marks

Pure recall, no working, no calculation. Static GK drawn from NCERT class 6 to 10 covers most of it, with history, polity and geography together usually accounting for more than half the section. Science sits at school level. Current affairs is typically four to six questions from the last six months. This is the best hours-to-marks trade in the paper and the section most candidates under-prepare because it cannot be reasoned out.

Quantitative Aptitude — arithmetic, not advanced maths

CHSL Maths is dominated by percentage, ratio, average, profit and loss, simple interest, time and work, and speed and distance. Geometry and algebra appear but stay elementary. Because the questions are short, calculation speed is the whole game: tables to 25, squares to 25, and the fraction-to-percentage conversions up to 1/20 will do more for this section than any new chapter. Budget eighteen to twenty minutes.

English — decided months in advance

Vocabulary is the bulk of CHSL English. Synonyms, antonyms, idioms, one-word substitution and spelling routinely make up half the section, and every one of those marks is decided by what you memorised beforehand rather than anything you do in the hall. Ten words a day with weekly revision, started early, is the single highest-return English habit. Error spotting and sentence improvement follow a small, repetitive rule set — agreement, tense, prepositions, articles, parallelism.

The Typing Test — Small Stage, Total Disqualification

The skill test adds nothing to your merit score, which is exactly why it gets ignored. But failing it removes you from the process entirely, no matter how well you scored in Tier II. Every year candidates who cleared the written stages lose the job at this step.

• LDC / JSA — 35 words per minute in English, or 30 wpm in Hindi, on a ten-minute passage.
• Data Entry Operator — 8,000 key depressions per hour, which works out to roughly 15 minutes of sustained accurate entry.
• Accuracy counts. Speed with a high error rate does not clear the standard.

Typing speed is built by daily repetition and cannot be crammed. Fifteen minutes a day for two months will take most people comfortably past 35 wpm; two panicked days before the test will not. Start in week one, practise on the keyboard layout you will face, and train on continuous passages rather than isolated word drills.

A Four-Month CHSL Study Plan

Five Mistakes That Cost People CHSL

1. Leaving the typing test until the end. It adds nothing to merit but disqualifies outright, and speed cannot be built in a fortnight.
2. Over-investing in Tier I. Its marks are discarded — once you are comfortably past the likely cut-off, every extra hour belongs to Tier II.
3. Treating English as secondary. It is 40 questions and 80 marks in Tier II, the largest single block in the paper.
4. Guessing freely because the paper feels easy. At −0.5 in a high-cut-off exam, two guesses undo a correct answer.
5. Skipping General Awareness because it cannot be reasoned out. It is 25 marks in seven minutes and the cheapest section in the exam.

Books and Resources

Note what is not on that list: advanced mathematics material written for SSC CGL Tier II. CHSL maths stays at Class 10 level, and hours spent on trigonometric identities or coordinate geometry are hours taken from calculation drill and vocabulary — the two things that actually move a CHSL score.

Exam Day

1. Take mocks at your actual slot time through the final fortnight so your concentration peaks when the paper does.
2. Run a fast first pass, answering only what resolves immediately and marking anything that needs thought.
3. Return on a second pass with a clear view of the clock, and decide then which marked questions are worth a considered guess.
4. Watch accuracy rather than attempts. At −0.5 in a high-cut-off exam, two blind guesses undo a correct answer.
5. Keep General Awareness early in your order. Seven minutes, twenty marks, and no working — leaving it last is how candidates lose marks they already knew.

How to Use Mock Tests for SSC CHSL

CHSL Tier I is 100 questions in 60 minutes with −0.5 per wrong answer, which makes it as much a test of selection as of knowledge. Mocks are where you learn which questions to leave.

• Take a baseline Tier I mock in your first week, then one a week during coverage and two or three a week in the final six weeks.
• After each mock, record section-wise attempts, accuracy and time. Your target is high accuracy across all four sections, not a heroic attempt count.
• Mark every guess. If more than a third of your guesses are wrong, stop guessing on questions where you have not ruled out two options.
• Review vocabulary questions you got wrong and add those words to your daily list. In CHSL, English errors repeat because the same words recur.

CHSL's Quant section is arithmetic-heavy, so watch for time drains. If one mensuration or algebra question takes more than ninety seconds, it is usually better to skip and return.

The Last 30 Days Before Tier I

1. Weeks 1–2: two to three full mocks a week with full analysis. Revise from your error log.
2. Week 3: sectional practice on your two weakest question types, plus daily vocabulary and current affairs revision.
3. Week 4: no new topics. Revise formulas, static GK notes, idioms and one-word substitutions. One light mock mid-week.
4. If you need the typing test, keep practising typing three or four times a week throughout. Typing speed fades faster than people expect.

Frequently Asked Questions

Where to Start This Week

The gap between reading a syllabus guide and beginning preparation is where most attempts quietly end. If you take nothing else from this, take the first three items below and do them in the next seven days.

1. Take one full CHSL Tier I mock today, cold, before studying anything. You need a baseline, and a score you did not prepare for is the only honest one you will get.
2. Start the typing practice. Fifteen minutes daily, on continuous passages, from this week — not the week the Tier II result arrives.
3. Begin the vocabulary habit: ten words a day, written down, revised every Sunday. Over four months that is the largest single block of CHSL English handled.
4. Open NCERT class 6 history and read one chapter. Static GK is the cheapest section in the paper and it accumulates only by starting.
5. Set a fixed daily slot and protect it. Consistency beats volume in every exam decided by recall and speed, and CHSL is decided by both.

Everything else in this guide — the section ordering, the accuracy targets, the Tier II focus — matters only once those habits are running. A candidate who does the five things above for four months will be ahead of one who read three syllabus guides and started next month.
