You cannot study your way to a higher intelligence in a week, but you can stop losing points you already have. Familiarity with the item formats, a pacing strategy, sleep and a calm setting are each worth a few points, and together they are worth roughly 5 to 8 points for someone who has never taken a timed test. Practice on the specific items of the test you will sit is the one thing that works best and is the one thing a supervised test will not let you do.
What the research says about practice effects
Take the same IQ test twice a month apart and the second score is typically 3–7 points higher. Take a parallel form (same structure, different items) and the gain is smaller, around 2–4 points. Most of this is familiarity: knowing what a matrix item is asking, how the timer works, that unanswered items score zero. The gain is real for the test and absent for the underlying ability, which is why test publishers recommend a year between administrations and why Mensa will not accept a score from a test you chose and took at home.
Coaching studies on cognitive ability tests used in hiring find a similar picture: a few points from format familiarity and strategy, then a plateau.
A one-week plan
- Days 1–2: learn the formats. Do one full-length practice test in each format you will meet — matrices, number series, verbal analogies, figure rotation. Review every item you got wrong until you can say what the rule was. Our Mensa-style matrix test and Fast & Accurate test cover the nonverbal formats; the standard test covers verbal and numerical ones.
- Days 3–4: work on pacing. Take a timed test and note where you lost time. The usual leak is spending three minutes on one hard item. Decide in advance on a per-item limit (about 45–60 seconds for most tests) and a rule: if you are stuck, pick the best remaining option and move on.
- Day 5: rest the brain. Light practice only. Cramming on day five does nothing; sleep debt on day seven costs real points.
- Day 6: logistics. Know where, when, what to bring, whether a break is allowed, whether guessing is penalised (on most tests it is not — never leave a blank).
- Day 7: the test. Eat normally, no extra caffeine, arrive early, warm up with five easy puzzles if you can.
Strategies for the common item types
Matrices. Read across the rows first, then down the columns. Name the rule for each attribute (shape, count, fill, position, rotation) before looking at the options; then eliminate options that break any rule. Most wrong answers break exactly one rule. The six rule types are described in Raven's matrices explained.
Number series. Check differences first, then ratios, then alternating patterns (every other number), then two interleaved series.
Verbal analogies. State the relationship in the first pair as a sentence (“a sculptor makes a statue”) and apply the sentence to the options.
Figure rotation. Pick one distinctive feature of the figure and track where it ends up; do not try to rotate the whole thing at once.
Working-memory tasks (digit span, memory grids). Chunk digits into groups of three; for grids, describe the pattern in words.
What does not work
Brain-training apps: they improve the trained task and little else. Nootropics and “smart drugs”: no replicated gain in healthy adults beyond the effect of caffeine on alertness. Memorising answer keys from leaked tests: unethical, and supervised tests rotate forms. Pulling an all-nighter to “practise more”: sleep deprivation costs more than any practice gains. The broader evidence on raising ability over months and years is in can you improve your IQ?.
If the test is online
Everything above applies, plus the environment is yours to control. Use a desktop or a tablet if you can, full screen, notifications off, nobody talking. Read the instructions page properly: it tells you the time limit, whether you can go back, and how the score is reported. Note from our data study that people who rushed the 25-question test in under three minutes averaged 17 points below those who took three to five minutes. Steady beats fast.
Frequently asked questions
Can you study for an IQ test?
You can prepare for the format, which is worth a few points. You cannot raise the underlying ability in a week. The gains from practice are largest for people who have never seen timed puzzle items before.
How many points can practice add?
Retaking the same test adds about 3–7 points; practising on similar but different items adds about 2–4. Sleep, pacing and a calm setting add a few more for people who otherwise lose them.
Should I guess on an IQ test?
Yes, on almost all tests: unanswered items score zero and wrong answers are not penalised. Eliminate what you can and pick the best remaining option.
How should I prepare for the Mensa test?
Do Mensa’s own practice test and two or three matrix tests of similar length to learn the format and pacing, then sleep well. Mensa’s supervised test uses forms you cannot practise on, so familiarity is all you can gain.
Practise the format
The Mensa-style test gives you 35 matrix puzzles under a real 25-minute limit, with a review of every puzzle afterwards.
