Score Improvement
“IQ maxxing” has become internet shorthand for optimizing your IQ test score — the same naming pattern as looksmaxxing or moneymaxxing, applied to reasoning tests. Some of what gets marketed under that label is real and useful. Some of it is exaggerated. This page separates the two, plainly.
Short version: you can't rewire your underlying fluid intelligence in a week, but you can control almost everything else that determines whether a test result reflects your actual reasoning — and that's where most of the real score movement comes from.
The “-maxxing” suffix comes from online self-improvement communities and gets applied to almost anything people try to optimize — appearance (looksmaxxing), finances (moneymaxxing), and increasingly, cognitive performance. Applied to IQ, it usually means one of two very different things: a genuine attempt to control every variable that affects a test result, or a marketing claim that a supplement, app, or course can permanently raise your intelligence.
This page is about the first kind. The evidence for durably raising fluid intelligence through short-term interventions is weak; the evidence for controlling testing conditions, format familiarity, and pacing is strong and well documented. That distinction is the entire difference between real IQ maxxing and a marketing claim.
Most of the score difference between a person's first and second attempt at an IQ-style test comes from three controllable sources, not a change in underlying ability.
Noise, interruptions, fatigue, and technical problems each cost real points. Test-retest research shows score swings of 5–10 points between sessions even under otherwise controlled conditions — a meaningful share of that is explained by environment alone.
First-time exposure to matrix-style reasoning items costs points independent of reasoning ability — you're solving the format and the problem simultaneously. A short amount of deliberate practice on the actual item types (see the Raven's matrices format guide) removes that overhead on subsequent attempts.
Overinvesting in one hard item at the expense of several easier ones is one of the most common and most fixable sources of lost points. A simple soft time cap per question protects your overall attempt far more than occasionally solving one very hard item.
Check off what's already true for your setup. This doesn't raise your fluid intelligence — it tells you how much of your next result will reflect real reasoning versus avoidable noise.

Process
This checklist tracks controllable testing conditions, not a method for raising fluid intelligence itself. It reflects how much of your result will represent your real reasoning rather than session noise.
Being direct about this protects you from wasting time and money on things that won't move the number — and it's the honest counterpart to the section above.
Research on commercial brain-training apps consistently shows gains transfer to the trained task itself, not to general fluid intelligence. You get better at the app's specific game, not measurably smarter overall.
No supplement has been shown in controlled research to produce a durable IQ increase. Some may modestly affect alertness or mood, which can indirectly help test performance — that's a testing-conditions effect, not a cognitive one.
This inflates a specific test's score without reflecting any underlying reasoning ability. It also stops working the moment the item set changes, which is the opposite of a repeatable skill.
IQ-style scores are deliberately built to be stable across short timeframes. Legitimate score movement happens through format familiarity and controlled conditions, not a one-week transformation.

IQ maxxing is internet shorthand — part of the same "-maxxing" family as looksmaxxing and moneymaxxing — for deliberately optimizing every controllable factor that affects your IQ test score: testing conditions, pacing, format familiarity, and review process. Used honestly, it describes a real and useful practice. Used as a claim that you can permanently raise your underlying intelligence in days, it overstates what any legitimate method can do.
You can max out how accurately a test reflects your real reasoning ability by controlling the variables that usually cause noise: poor conditions, unfamiliarity with the item format, and rushed pacing. What you can't do is durably raise your underlying fluid intelligence in a short window — that's a much slower-moving trait. Most of the score gain people experience between a first and second attempt comes from removing friction, not from getting smarter.
Close, but not identical. "Studying" implies learning content; IQ-style tests are largely format-based, so the equivalent is practicing the item types (rotation, progression, logical overlay patterns) and your pacing strategy — not memorizing facts. The goal is fluency with the format, not memorization of specific answers.
Test-retest research on cognitive assessments shows typical swings of 5–10 points even under controlled conditions, mostly from removing environmental noise and format unfamiliarity on the first attempt. Larger jumps usually indicate the first session had a specific fixable problem — poor conditions, misunderstood instructions, severe time pressure — rather than a sudden capability change.
Testing conditions and pacing, in that order. They're free, immediate, and typically explain more score variance than anything else on this list. Format familiarity is second — a few practice items on the actual pattern types used matters more than generic "brain training."
