High-yield summaries for fast review before test day
English/Spanish study access - the DET is administered in English; Spanish is a study-accessibility aid for the explanations and strategy

Independent prep product; not affiliated with, sponsored by, or endorsed by Duolingo
Reading & Read-and-Complete
Short academic passages and read-and-complete items: main idea, detail, inference, vocabulary-in-context, and best-word completion in the DET style.
Listening Comprehension
Transcript-based spoken passages and conversations: main idea, detail, speaker attitude/function, and listen-and-comprehend accuracy.
Vocabulary & Real/Fake Word Recognition
Real-vs-fake English word recognition (morphology cues), closest-in-meaning vocabulary, word families, collocations, and register.
Grammar & Language Use
Subject-verb agreement, tense and parallelism, articles/prepositions, relative clauses and conditionals, modifiers, and sentence combining.
Writing & Speaking Strategy
Strategy and evaluation for the writing and speaking tasks: clear description, thesis and support, coherence, scoring criteria, and the errors that lower a score.
