"Write About the Photo": how it's actually scored

The photo-description task looks simple, which is exactly why unprepared answers lose points. Here is what the scoring rewards.

Content accuracy

Describe what is actually in the photo — people, actions, setting — before adding interpretation.

Grammatical range

Mix simple and complex sentences. One clean relative clause beats three broken ones.

Vocabulary precision

Name specific objects and actions ("a crowded platform", "leaning against") instead of "some things" and "stuff".

Time management

You get one minute. A strong response is 3–5 accurate sentences, not a rushed paragraph.

Practice photo descriptions with AI feedback that checks all four criteria on every attempt — try it free.

DET myths that cost test takers

Myth: The DET is the easy test.

The adaptive format means questions get harder as you answer well. Universities accept it because it discriminates ability — treat prep like the real thing.

Myth: Template intros guarantee a good speaking score.

The scoring rewards natural, task-specific responses. A memorized template that ignores the prompt scores worse than a simple direct answer.

Myth: You can’t prepare for an adaptive test.

You can’t memorize questions, but you can train the skills the rubric measures — fluency, precision, and structure — which is exactly what daily AI feedback targets.
