Get to know the games
Recall it. Use it. Return to it.
Start at an advanced level, retrieve a word without answer choices, complete a sentence in context, then assemble a sentence from meaningful chunks. Each item includes an original example, common collocations and a note on register or usage.
Practice arguments, synthesis, research paragraphs and university emails. Compare your draft with an annotated model, revise it, and save it in your notebook. Missed items return sooner; successful recall spreads reviews over longer intervals.
- Is this an official TOEFL or GRE test?
No. These original exercises develop academic English skills relevant to study and exam preparation. Difficulty labels are editorial guides, not certified CEFR ratings. Practice results are not exam scores.
- Are my drafts automatically graded by AI?
The writing workshop provides word counts, target-expression checks, structural observations and annotated models. It does not provide AI grammar correction or an official writing score. Saved drafts and study progress can be recovered with your civilization recovery code.
