What this service is
DET Mock Tests provides practice tests for the Duolingo English Test. It is a preparation tool.
No affiliation with Duolingo
We are not affiliated with, endorsed by, or connected to Duolingo, Inc. "Duolingo" and "Duolingo English Test" are trademarks of Duolingo, Inc. We use those names only to describe what this service prepares you for. The official test must be booked through Duolingo.
Scores produced here are estimates
Scores from this site are generated by our own scoring engine. They are not official Duolingo English Test results, they are not accepted by any institution, and they do not predict your official score. Our question difficulties are our own estimates and have not been calibrated against official test-taker data. Do not make decisions that depend on a score being accurate without confirming it against an official result.
Acceptable use
Do not scrape, republish or resell the question bank. Do not attempt to access other users' data. Do not use the service to build a competing question bank.
Availability
Provided as-is, with no guarantee of uptime. Features may change. We may discontinue the service, and will give notice before deleting user data if we do.
