Grammar practice — CEFR 2
The wrong options here are not machine-invented. Every CEFR 2 grammar point ships with a minimal wrong/right pair written by the author — the exact error Vietnamese learners make — and that pair is placed back into a real example sentence with its Vietnamese meaning, so the answer is unique. The second format shows a sentence and asks for its pattern, with three distractor patterns drawn from points in the SAME category, close enough that you have to read carefully.
Sample question
already, yet, just, ever, never
Tôi chưa bao giờ thử sushi.
✓ I have never tried sushi.

FAQ
Are the wrong options generated by a machine?
No. Every grammar point carries an authored wrong/right pair — a real error Vietnamese learners make. Inventing grammar distractors badly teaches the error itself, so every option here is text a human wrote.
How is this different from the grammar practice inside the course?
Same question generator, different scope: here it is pinned to one CEFR level, so both the questions and the distractors stay inside the level you are studying, whereas the course drills a part or the whole syllabus.
