The SSC CHSL syllabus, analysed

The official SSC CHSL syllabus is a list of topic names. It tells you what can be asked but not at what level or how often, and those two questions decide how you spend your months. Asked properly, the answers are reassuring. The maths rarely goes beyond Class 10. The English tests rules and words you can learn. Reasoning follows a fixed set of patterns. General awareness leans on school science and static facts. CHSL doesn't demand advanced knowledge. It demands accuracy and speed on familiar material.

How the syllabus maps to the exam

The same four subjects appear in both tiers, but the weight and the stakes change.

Read the right-hand column twice. English is the single biggest block of merit marks. Maths and reasoning together are worth 180. GA, which many candidates spend the most hours on, is worth 60. That doesn't mean ignore GA. It means don't let it eat the time English and maths need. The exam pattern guide covers timing and negative marking.

Quantitative Aptitude

The level, shown by an example. A shopkeeper marks an article 25% above cost and gives a 10% discount. Find the profit per cent. Take cost = 100. Marked price = 125. Selling price = 90% of 125 = 112.5. Profit = 12.5%. Nothing here is beyond Class 10. The challenge is doing it in under 40 seconds without an error.

General Intelligence and Reasoning

Reasoning rewards pattern familiarity more than any other subject. Once you have seen fifty coding questions, the fifty-first takes twenty seconds.

Example. Find the next term: 3, 7, 15, 31, ? Each term is double the previous plus one: 3 × 2 + 1 = 7, 7 × 2 + 1 = 15, 15 × 2 + 1 = 31, so the next is 31 × 2 + 1 = 63.

English

Tier 2 English has 40 questions, so it includes longer comprehension work than Tier 1. Most grammar questions test a small set of rules again and again: subject–verb agreement, tenses, prepositions, articles, pronoun case and comparatives.

Example. Spot the error: "Each of the students have submitted their assignment." The subject is "each", which is singular, so the verb should be "has".

General Awareness

GA is the one subject where you can't reason your way to an answer. Either you have seen the fact or you haven't. The best return comes from NCERT-level science and repeated static GK, because these recur across SSC exams.

Computer Knowledge (Tier 2, qualifying)

• Basics: hardware, software, input and output devices, memory units, operating systems.
• Software: Windows, and MS Office (Word, Excel, PowerPoint) features and shortcuts.
• Internet and email: browsers, URLs, email terms, search.
• Networking and security: LAN, WAN, viruses, firewalls, safe practices.

It is qualifying, so it doesn't add to your rank, but failing it ends your candidature. Two or three focused weeks are usually enough. See our computer knowledge guide.

The skill test (Tier 2, Session II)

• LDC/JSA: typing at 35 words per minute in English or 30 words per minute in Hindi, in 10 minutes.
• DEO: a Data Entry Speed Test of 8,000 key depressions per hour for most offices, and 15,000 for the offices that need science with maths, in 15 minutes.

Typing speed can't be crammed, so it belongs in your syllabus from the first week.

Priorities and sources

1. Arithmetic and English grammar: the largest share of scoring questions.
2. Reasoning: quick gains from daily practice.
3. GA science and static GK: good return for time spent.
4. Geometry and trigonometry: enough to answer standard questions.
5. Typing: steady daily practice from the start.

For sources, use NCERT Class 6–10 maths and science, one standard book each for quantitative aptitude, reasoning and English grammar, a concise GK book, a monthly current affairs compilation, and previous years' CHSL papers, which are the best guide to level. Our previous papers guide explains how to use them.

Practice

1. Which Tier 2 module carries the most marks?
2. Find the next term: 2, 6, 12, 20, 30, ?
3. Correct the sentence: "Neither the manager nor his assistants was present."
4. Cost price ₹400, sold at ₹460. Profit per cent?
5. Which two Tier 2 components are qualifying?

Answers:

1. English: 40 questions, 120 marks.
2. 42. The differences are 4, 6, 8, 10, so the next difference is 12: 30 + 12 = 42.
3. "…nor his assistants were present." With "neither…nor", the verb agrees with the nearer subject, "assistants", which is plural.
4. Profit = 60; 60 ÷ 400 × 100 = 15%.
5. Computer Knowledge and the skill test.

What to do next

• Print the syllabus from your notification and mark each line strong, average or weak.
• Solve one previous CHSL paper untimed to see the real level.
• Start typing practice this week, 15–20 minutes a day.
• Build a weekly timetable that gives English and maths the most hours. The four-month plan shows one way to do it.
