What goes in here
Anything a reader would want to know: a new test or guide, a change to scoring, a wrong figure or a broken question fixed, a claim we removed. Small wording edits and design changes are not listed. If you reported a mistake, the fix appears here once it is live. To report one, see the corrections policy.

- New
How we make our tests, sources and corrections
A method page for every test, explaining how the questions are written and checked and exactly how each score is calculated, including what we have not measured yet. A public list of the sources we cite, numbered references on the IQ concept pages, a corrections policy and this change log.
- Updated
More practice tests for every aptitude exam
Extra full-length practice tests and topic drills for the CCAT, Wonderlic, ASVAB, TEAS and reasoning tests, built from about 320 new hand-written questions. No hand-written question repeats between practice tests.
- New
Employer assessment guides
Guides to the online tests used by 17 employers, each separating what the employer states from what candidates report.
- New
Numerical and verbal reasoning practice test
A 50-question practice test in the style of graduate reasoning tests: 25 table questions with computed answers, then 25 True, False or Cannot say questions. The verbal passages were checked by a second, independent pass. Pass marks are labelled as what candidates report, not employer data.
- New
TEAS practice test for nursing applicants
A 50-question practice test across reading, maths, science and English with an estimated ATI level. The level cut-offs differ by about a point between published sources, which the result says.
- New
ASVAB practice test and AFQT calculator
A 50-question practice test on the four AFQT subjects with an estimated AFQT percentile. Branch minimums are marked "confirm with a recruiter" because services change them.
- New
CCAT and Wonderlic practice tests
Timed practice tests in the style of the CCAT (50 questions, 15 minutes) and the Wonderlic (50 questions, 12 minutes), with an estimated percentile among real test-takers.
- New
IQ concept guides
Seven guides that explain the ideas behind IQ scores: the average, what counts as good, standard deviation, the Flynn effect, the g factor, heritability, and IQ and income. Each one names its studies.
- Correction
Wrong comparison and reliability figures fixed
Some IQ score tools showed comparison and reliability figures that did not match their sources. They now share one maths library and use the published figures.
- Correction
Claims we could not support removed
We removed every remaining "free IQ test", "accurate" and "scientifically validated" claim, and cut unsourced statements from older articles.
- Correction
Processing-speed claim corrected
The average IQ by age pages overstated how early processing speed declines. The text now follows Hartshorne and Germine (2015).
- Removed
Expert bylines that were not real people
Earlier versions of some articles carried the names of individual experts who were not real, verifiable people. We removed them and rewrote the articles under the LifeScore Editorial Team.

IQ test: every question re-checked
We re-checked all 25 questions, their 125 answer choices and the answer keys. Repairs included a cube net missing its sixth face, a 3D footprint question whose drawing was ambiguous, a number grid whose hint contradicted the picture, a sequence with an inconsistent rule, an analogy with an underdetermined colour rule, and three rule questions with missing or conflicting instructions. Two sequence questions also lost hints that gave the answer away.
