About this logical thinking test
This test is about reasoning from rules. You will draw conclusions from statements, put people or objects in order, work out what an if-then rule does and does not prove, and solve short puzzles. These skills matter in exams, law, computing and everyday decisions.
How to get the most from it
Read each statement slowly and ask what must be true, not what might be true. For ordering questions, sketch a quick line. Watch for the classic trap in conditional logic: "if A then B" does not mean "if B then A".
What this test practises
Deduction means reaching a conclusion that must be true if the given statements are true. That is different from a guess about what is probably true. Careful deduction is used when you read a contract, test a computer program, follow a legal argument, or check whether a claim in an advertisement really follows from the evidence. The test separates conclusions that must follow from conclusions that only sound sensible.
A worked example
Ordering: Anna is taller than Ben. Ben is taller than Chloe. Dev is shorter than Chloe. Who is the shortest?
Answer: Dev. Sketch the order from tallest to shortest: Anna, Ben, Chloe, Dev.
If-then rule: If it rains, the match is cancelled. The match was cancelled. Did it rain?
Answer: We cannot tell. The rule says that rain leads to cancellation; it does not say that rain is the only reason for cancellation. The match could have been cancelled because of a power cut or a shortage of staff.
Common mistakes and how to avoid them
Turning “if A then B” into “if B then A”.
Reading “some” as if it meant “all”.
Bringing in outside knowledge instead of using only the statements you are given.
Assuming an order or a link that the question never states.
Your mark out of 100 shows how you did on these 50 questions on one day. It is not an IQ number, because a real IQ score comes from a standardised test given and interpreted by a qualified psychologist and compared with a large norm group. Use the section scores to choose what to practise, and retake the test after a week or two to see progress. Tiredness, noise and stress change results, so one low score is not a verdict on your ability.
