Cookies and advertising

Last updated: 2026-11-09. Drafted from FINE-PRINT.md. The cookie list is filled at build time from the tools actually in use, and no tool is added to the site before it is added to that list.

What a cookie does here

A cookie is a small file a website asks your browser to keep. We and our partners use cookies, and similar tools such as pixels and device identifiers, for four jobs: running the site (keeping a test in progress and remembering a language choice), counting and improving (analytics), advertising (showing ads, limiting repeats, and measuring them), and remembering the cookie choices you made here.

Advertising pays for this site

Every test on this site is free. Advertising is the reason. We use [ad network] and its partners. Those partners may collect information about your activity on this and other sites to show ads and to measure them. We do not control the ads a partner serves on a given visit, and an ad is not our recommendation. We block ad categories that would mislead a test taker where the network lets us, including ads that promise a credential this site does not issue. If you see an ad that promises a pass, a card, or an official result, tell us at [email protected] with the page you were on.

Consent, and Do Not Sell or Share

A consent tool runs on this site from the first visit. It records the choices you make here, and you can change them at any time from the cookie settings link in the footer. If you are visiting from the European Economic Area, the United Kingdom, or Switzerland, ads are not personalised unless you agree to it.

A Do Not Sell or Share link sits in the footer of every page. Using it, or sending a global privacy control signal from your browser, opts you out of the sale or sharing of personal information and of targeted advertising for that browser. There is no charge and no difference in the tests you can take.

Your choices

Cookie settings: [link]. You can turn off analytics cookies and personalised advertising cookies there. Needed cookies stay on, because the features they support will not work without them. You can also change ad personalisation in your Google account, use the opt out pages run by the Digital Advertising Alliance and the Network Advertising Initiative, or block or delete cookies in your browser. Your practice progress on this device is stored in the browser, so deleting site data deletes that progress.

Cookie list and changes

To be filled at build time from the tools actually in use, and kept current. Format: name, who sets it, what it does, how long it lasts. If our partners or our tools change, this page changes, and the date at the top changes with it.
