Official syllabus
Tier 1: 25 questions · 50 marks · 10+2 level
CHSL quant stops at 10+2 level, which is a genuinely lower ceiling than CGL Tier 2 — so the most common overspend here is buying advance-maths books written for CGL. Arithmetic and speed matter far more than depth.
| Book | Author / publisher | Covers | Why it matters |
|---|---|---|---|
| Fast Track Objective Arithmetic | Rajesh Verma (Arihant) | Arithmetic | Pitched at exactly the CHSL level with shortcut-first methods. |
| NCERT Mathematics (Classes 8–10) | NCERT | Foundation | Free official source; CHSL arithmetic sits on this base. |
| SSC CHSL previous year papers | Kiran | Practice | The clearest signal of how much easier CHSL is than CGL. |
Tier 1: 25 questions · 50 marks
Reasoning at CHSL level is pattern-heavy and shares almost all of its ground with CGL, which is why a single reasoning book serves both if you are attempting them in the same cycle.
| Book | Author / publisher | Covers | Why it matters |
|---|---|---|---|
| A Modern Approach to Verbal & Non-Verbal Reasoning | R.S. Aggarwal | Reasoning | Shared with CGL — one book covers both exams. |
| SSC CHSL reasoning practice sets | Kiran | Practice | Timed sectional sets at CHSL difficulty rather than CGL. |
Tier 1: 25 questions · 50 marks
English carries the same 50 marks as every other section and is the most improvable of the four. At CHSL level the grammar chapters of a standard reference are enough — the advanced practice sets written for CGL are the wrong tool.
| Book | Author / publisher | Covers | Why it matters |
|---|---|---|---|
| Objective General English | S.P. Bakshi | Grammar | Use the grammar and vocabulary chapters; skip the advanced sets. |
| Word Power Made Easy | Norman Lewis | Vocabulary | Vocabulary building that transfers to every other SSC exam. |
Tier 1: 25 questions · 50 marks
Static GK plus current affairs, exactly as in CGL. If you are preparing both exams, this is the section where the overlap is total and you should not buy twice.
| Book | Author / publisher | Covers | Why it matters |
|---|---|---|---|
| Lucent’s General Knowledge | Lucent | Static GK | The same volume that serves CGL, CHSL, GD and MTS. |
| Monthly current affairs compilation | Any current publisher | Current affairs | A free monthly PDF is enough for this section. |
Where books stop
The syllabus overlaps heavily with CGL but the ceiling is lower, so buying CGL Tier 2 material for CHSL wastes both money and study time. The stage most candidates neglect is the one after the written paper: DEO and LDC posts carry a typing or data-entry skill test, and it is qualifying. Start typing practice alongside the written preparation rather than after your result.

Common questions
Fast Track Objective Arithmetic for quant, R.S. Aggarwal for reasoning, S.P. Bakshi for English grammar and Lucent for general awareness is the common combination. Because CHSL stops at 10+2 level, avoid CGL Tier 2 advance-maths books — they cover material CHSL does not ask.
For reasoning, English and general awareness, yes — the overlap is close to total and a single set serves both. Quant is where they diverge: CGL Tier 2 goes considerably deeper, so CGL aspirants need an advance-maths book that CHSL candidates do not.
Yes. LDC and DEO posts include a typing or data-entry skill test after the written stage, and it is qualifying in nature. It is the most commonly under-prepared part of CHSL because candidates leave it until after the results.
