A note on DET format DET is adaptive (questions get harder or easier based on your answers) and combines short, varied task types rather than long passages or essays — so no single exercise here will feel exactly like the real test. That said, the picture-based vocabulary exercises and listen-and-type spelling practice are genuinely close matches for two of DET's core task types, which makes this page a better-than-average fit despite DET's unusual format. Acceptance varies by institution, so always confirm with your specific school before relying on a DET score, and try the official free DET practice test before exam day.
