Logical Reasoning Test: 20 Questions, 20 Minutes
Twenty short arguments, twenty minutes — about a minute each. Nothing is marked while you work; when the clock stops you get a score, a breakdown by question type, and the reasoning behind every option. Everything you need is in the passage: no outside knowledge is required, and no answer depends on what you happen to believe.
A logical reasoning test gives you a short argument and asks a single question about it: what must the argument assume, what would weaken it, what is wrong with the way it reasons. There is no general knowledge in it and no maths — everything you need is in the passage, and the answer never depends on what you personally believe.
Formats like this sit in front of a lot of doors. Graduate schemes and consulting firms screen with critical-reasoning papers, law schools test the same skill as LSAT Logical Reasoning, and the GRE and GMAT both lean on it. Employers usually give you about a minute per question, which is why this paper runs 20 questions in 20 minutes rather than letting you take as long as you like.
Scoring is one point per question with no penalty for a wrong answer, so never leave a question blank. Nothing is marked while you work. When you submit — or when the clock runs out — you get your score, your accuracy split across the six question types, and a full explanation of every question, including why each wrong option was written to look right.

Frequently asked questions
Is this a real logical reasoning test?
The 20 questions are original, written in the style used by graduate-scheme critical reasoning papers and LSAT Logical Reasoning. They are not retired questions from any commercial test, so nobody has memorised the answers. The format, the timing and the question types match what those papers actually ask.
How long is it and can I pause?
20 questions in 20 minutes, roughly a minute each. The clock starts when you press start and does not pause — that is the point of a timed paper. You can jump between questions and change answers as often as you like before you submit.
What is a good score?
Most graduate schemes screen somewhere around 60-70 percent on papers of this kind, so 13 or 14 out of 20 is a reasonable working target. Treat the by-type breakdown as the more useful number: a 14 built on one collapsed question type tells you far more about what to practise than the total does.
Do I get the answers explained?
Yes, every question, after you submit. Each explanation says why the correct option is correct and why the tempting wrong ones fail — that second half is where the learning is, because on this format the wrong answers are usually true statements that simply do not do the job the question asked for.
Is it free and do I need an account?
It is free and there is no sign-up. An account only becomes useful if you want your scores and your wrong answers saved between attempts.
What is the difference between this and your logical reasoning questions page?
This page is the timed exam: no feedback until you submit. If you would rather read the questions grouped by type with worked explanations open in front of you, use the logical reasoning questions page instead — same discipline, opposite mode.
