IQ Test Questions and Answers: Free Samples and PDF
You search for IQ test questions and answers, and you find a dozen PDFs with different layouts, different scoring tables, and no sign of who wrote them. Which ones are worth your time? This guide gives you IQ test questions and answers you can try right now, then shows how to check any PDF before you trust the number it hands back.
Every question below is written for practice. None of them comes from a copyrighted clinical test, and none of them can give you an official score.
Ten Sample IQ Test Questions With Answers
The short version: most IQ test questions fall into four families, which are number patterns, letter patterns, verbal logic, and visual or spatial reasoning. Below are two or three of each. Cover the answers, give yourself about 30 seconds per question, then check.
Number and Letter Patterns
Question 1. What comes next? 2, 5, 10, 17, 26, ?
Question 2. What comes next? 1, 2, 4, 7, 11, 16, ?
Question 3. What comes next? 5, 10, 6, 12, 7, 14, ?
Question 4. What comes next? A, C, F, J, O, ?
Verbal Logic
Question 5. Hand is to glove as foot is to what?
Question 6. Which one does not belong? Square, triangle, cube, circle.
Question 7. All bloops are razzies. All razzies are lazzies. Are all bloops definitely lazzies?
Visual and Spatial Reasoning
Question 8. Each row follows the same rule. Row one has 1 dot, 2 dots, 3 dots. Row two has 2 dots, 3 dots, 4 dots. Row three has 3 dots, 4 dots, and a missing cell. How many dots go in the missing cell?
Question 9. You turn the lowercase letter "b" upside down by rotating the page 180 degrees. Which letter do you see?
Question 10. A square sheet of paper is folded in half, then folded in half again in the same direction, and one hole is punched through all layers. How many holes appear when you unfold it fully?
Answers and How to Solve Each One
| # | Answer | Why |
|---|---|---|
| 1 | 37 | The gaps grow by 2 each time: +3, +5, +7, +9, so the next gap is +11. |
| 2 | 22 | The gaps are +1, +2, +3, +4, +5, so the next is +6, and 16 + 6 = 22. |
| 3 | 8 | Two sequences are interleaved. The odd positions count up 5, 6, 7, 8 and the even positions rise by 2: 10, 12, 14. |
| 4 | U | Letter positions are 1, 3, 6, 10, 15. The gaps are 2, 3, 4, 5, so the next gap is 6, which lands on position 21, the letter U. |
| 5 | Sock (or shoe) | A glove covers a hand the way a sock covers a foot. |
| 6 | Cube | The other three are flat shapes. A cube is three-dimensional. |
| 7 | Yes | If every bloop is a razzie and every razzie is a lazzie, every bloop is a lazzie. |
| 8 | 5 | Each row starts one higher than the row above and adds one per cell, so row three is 3, 4, 5. |
| 9 | q | A 180-degree rotation flips both left and right and top and bottom. |
| 10 | 4 | Two folds make four layers. Each layer carries one hole, so you get 4. |
If you got seven or more right in about five minutes, the question types are probably familiar to you. If you got fewer, that is useful information too: it tells you which family to practice. A short quiz like this cannot tell you your IQ. It only shows how comfortable you are with the formats.
A Quick Method for Pattern Questions
For number sequences, work through the same short checklist every time. First, subtract neighboring terms. If the gaps are not constant, subtract the gaps. If the numbers jump around, split them into odd and even positions. If nothing fits, test multiplication or squares. Most written sequences fall to one of these four moves.
For matrix questions, check rows first, then columns, and only then look at the answer options. Reading the options first tends to pull you toward an answer that looks right but breaks the rule in one cell.

Are IQ Test Questions and Answers in a PDF Worth Using?
A PDF can be a perfectly good way to practice. It is easy to print, there is no timer pressure from a website, and you can work with a pencil. The risk is not the file format. The risk is that anyone can publish a PDF and attach a score table to it, and nothing checks whether that table means anything.
Use this checklist before you trust a printable test:
| Check | Good sign | Warning sign |
|---|---|---|
| Author | A named publisher or organization you can look up | No author, no source, re-uploaded copies |
| Answer key | Every answer comes with a reason | Answers only, or no key at all |
| Scoring table | Says clearly that it is an estimate for practice | Promises an exact IQ from a few pages |
| Number of items | Enough questions to mix several question families | Five or ten questions, then an IQ result |
| Copyright | Original questions | Pages copied from a commercial test |
The last row matters more than people expect. Real clinical tests are copyrighted and are given by a trained examiner, so a free PDF that claims to be a leaked or complete version of one is almost certainly not what it says. Treat it as a puzzle sheet.
What a PDF Cannot Do
A printable sheet has no norm group behind it, which means it cannot tell you where you stand compared with other people your age. Mensa says this plainly about its own free practice material: its online IQ Challenge is not an official IQ test and cannot be used to qualify for membership. To qualify, you need a score in the top 2 percent of the population on a test administered by Mensa or on another approved test.
That is the right way to think about any free PDF. It is a workout, not a measurement.
What Do the Real Question Formats Look Like?
The most famous nonverbal format is Raven's Progressive Matrices. According to a Lancaster University psychology glossary, the standard test presents 60 abstract geometric patterns that get harder as you go. Each pattern has a missing part, and you choose the answer from 6 to 8 options. It is generally described as a measure of nonverbal, fluid reasoning, although the same entry notes that the claim that it is fully culture fair has been challenged by cross-cultural research.
For practice, that tells you what to train: spotting rules in shapes, quickly, without words. The text-based matrix in Question 8 is a simplified version of the same idea.
Building a Better Practice Sheet
If you want a printable set that is actually useful, build one yourself from mixed sources instead of downloading a single file:
- Pick three question families and write four items for each.
- Put the answers on a separate page, with one line explaining the rule.
- Time yourself at 30 to 45 seconds per item for the first pass.
- Mark every miss with the family it belongs to, then retry that family a day later.
This habit is more valuable than a high number on any sheet, because the explanation you write is what builds the skill. For more worked examples in the same style, see our guide to Mensa-style practice questions.
How to Use Your Results
Treat your result as a snapshot of how you handled a specific set of items on a specific day. Sleep, stress, and time pressure all move it. Score differences of a few points between two practice sheets mean nothing, and a result from a short sheet should never be used for school, work, or medical decisions.
If you want something longer than a sheet of ten questions, the test on iq-test-official.site covers several areas of reasoning and gives an estimate. Treat that estimate as a self-assessment, not an official or clinical result. If you need a formal assessment for a diagnosis, a school placement, or a support plan, that is a conversation for a qualified psychologist, not a website.
Summary
- Ten sample questions with answers are on this page. They cover number patterns, letter patterns, verbal logic, and spatial reasoning.
- A PDF is fine for practice if it names its author, explains every answer, and does not promise an exact IQ.
- Free printable sheets and online practice tests cannot replace a supervised test. Mensa says the same about its own free practice test.
- The standard Raven's matrices use 60 patterns, so train on spotting shapes and rules, not on memorized answers.
- Build your own sheet by mixing question families and writing a one-line reason for each answer.
Frequently Asked Questions
Q: Where can I find IQ test questions and answers in a PDF?
A: Look for a named publisher with an explained answer key. Libraries, school resource pages, and puzzle-book publishers often provide printable practice material. Avoid files with no author, answers only, or a guaranteed IQ result. You can also write your own sheet from the question families in this guide.
Q: Can a free IQ test PDF tell me my real IQ?
A: No, it can only give a rough practice indication. A real IQ score depends on a standardized test with a norm group and, for official results, a trained examiner. A PDF has neither, so use it to learn the formats rather than to get a number.
Q: How many questions should a practice test have?
A: More than ten if you want a meaningful signal. A very short sheet covers too few question families and is easily thrown off by one confusing item. Longer mixed sets give a steadier picture, though they still do not make the result official.
Q: Will practicing IQ questions raise my score?
A: It will mostly make you faster and calmer. Knowing the formats removes surprise and saves time, which helps on timed tests. It does not change the underlying ability a test is trying to estimate, so expect small gains from familiarity, not large ones.
Q: Can I use a free online or PDF test to join Mensa?
A: No. Mensa says its online practice test cannot be used for admission. You need to take a test administered by Mensa or submit a qualifying score from another approved test.
