SSC CGL & CHSL Tier 1: 1,000 Practice Questions

One thousand questions for SSC CGL and CHSL Tier 1 — every one original, every answer explained.

Written in the pattern of the previous years' papers: the same topics, the same kinds of question and the same level of difficulty that the Staff Selection Commission sets year after year. Four parts follow the four sections of the Tier 1 paper — General Intelligence and Reasoning, General Awareness, Quantitative Aptitude and English — in 59 topic chapters. Each chapter opens with one working idea for its topic and ends with the answers and a clear explanation of every one.

Checked before it was published. Every maths and reasoning answer was worked out and then checked by computer with exact fractions; every seating puzzle and syllogism has exactly one valid answer; the general awareness questions keep to settled facts that do not date.

Two full mock tests of 100 questions each, in the real Tier 1 format: four sections of 25, 60 minutes, two marks for a right answer and 0.50 off for a wrong one, with the 15-minute timer per section introduced for 2026.

It opens with the exam at a glance — the pattern, what each section tests, and the arithmetic of negative marking. That section and the first chapter are in the free sample.

Every question is original; none is copied from a Commission paper or another book. This book is independent and not endorsed by the Staff Selection Commission. Confirm the pattern with the notification for your examination.
