## What is UPSC CSAT Prelims II Quiz?

The paper that quietly ends campaigns. CSAT Prelims gets you over the 33%
qualifying line of UPSC Prelims Paper II — and then comfortably past it.

80 questions. 2 hours. Practice is organised into the three sections the exam
actually tests, with a worked explanation behind every answer. No account, no
sign-up. Everything works offline.

COMPREHENSION
68 original passages with 176 linked questions across ecology, governance and
science — inference-heavy, exam-style, and timed if you want them to be.

REASONING
275 questions on logic, syllogisms, coding-decoding, series, directions,
arrangements and puzzles — each one explained step by step.

NUMERACY & DATA INTERPRETATION
345 questions of aptitude maths and chart reading: ratios, averages, speed-
work-mensuration, and bar / line / pie / table  data interpretation.

SPEED MODE
The single best fix for the timing problem that sinks most aspirants. Speed
Mode throws 20 random questions at you with a per-question countdown (75-90s)
and auto-submits on timeout.

DASHBOARD
Track your average reading speed in words-per-minute, your comprehension
accuracy and your Speed Mode history over time.

TEST SETUP
Build per-section practice with negative marking to mirror real exam pressure.
Every chapter also keeps the Notes, Cards, Tricks and Quiz tools.

FREE TO START
CSAT Prelims is free to download, with starter sets unlocked in every section.
Try every tool before you decide to buy.
