Terms of Service

IQ Test Center provides an online cognitive assessment for personal insight and educational use. You agree to use the site lawfully and not attempt to disrupt, scrape, reverse engineer, or misuse the assessment system.

Scores are educational estimates based on responses, timing data, scoring rules, and modelled age-banded score-conversion tables used by the site. They are not calibrated against a representative standardization sample and are not a medical, psychological, educational, employment, or legal determination.

Do not use IQ Test Center as the only basis for important decisions about diagnosis, placement, hiring, admission, disability status, or treatment.

This is an IQ-style educational assessment. Exploration directions are broad suggestions based on performance in five task types; they are not professional, clinical, educational-placement, or employment advice.

You may create a free account to save a result so you can reopen it from another device. An account does not unlock a report — that requires the one-time payment described below. You are responsible for keeping your login credentials secure and for activity under your account.

Taking the assessment is free. Unlocking the report — educational composite score estimate, indicative percentile, five-domain breakdown, written interpretation, exploration directions and print-ready report — requires a one-time $7.99 payment. It is not a subscription, and the price is stated before the assessment begins. Payments are processed by Stripe and are subject to Stripe checkout terms.

Because digital reports may be generated or delivered immediately, refunds are not guaranteed after delivery. If a technical issue prevents report access, contact support so the issue can be reviewed.

SAT Prep Plus is an optional monthly subscription for the SAT® Prep section. It costs $5.00 per month and renews automatically each month until it is cancelled. Payment is taken by Stripe; we never see or store your card details.

New subscriptions begin with a 7-day free trial. You are not charged during the trial. At the end of the 7th day the first $5.00 payment is taken automatically unless you have cancelled before then, and the same amount is taken on the same date each month thereafter.

You can cancel at any time, including during the trial, using the "Manage or cancel membership" button on the pricing page. It opens the Stripe customer portal, where you can also update your card and read past invoices. Cancelling stops future renewals; it does not refund the current period, and you keep access until the end of the period you have already paid for.

Cancelling does not delete anything. Your practice history stays on your account after the subscription ends, so that resubscribing later restores it rather than starting from nothing. To have it removed, send a privacy request as described in the Privacy Policy; we verify that the request is yours before acting on it.

The subscription buys convenience, not access to study material. Everything in the SAT® Prep section — every practice question and worked explanation, every 48-question timed practice form sat online, every skill guide, reference and practice game — is free to use without an account or payment, and remains so. SAT Prep Plus adds printable PDF versions of the mock exam papers and the practice pack, and keeps your practice history across devices.

Cross-device practice history means that when you are signed in, the questions you mark as missed are stored on our servers against your account so the same list is available on another device. The record is a list of question identifiers, the dates you practised, and per-day round counts. It contains no free text, is visible only to you, and is never used to profile you or to inform any cognitive assessment result. You can practise with it switched off simply by not signing in — the same feature runs locally in your browser for everyone else.

The price may change in future. If it does, existing subscribers will be told before a changed amount is charged and can cancel first.

We work to keep the site available, but we do not guarantee uninterrupted service, permanent storage of all results, or error-free operation.

IQ Test Center may update these terms from time to time. Continued use of the site after updates means you accept the revised terms.
