Before you set off
A few bearings.
What makes the reviews different?
The target word returns through spaced repetition, with changing examples drawn from a shared sentence collection. You practise recognising the word in different contexts. Examples can reappear over time.
How do conversations work?
Engage chapters are conversations built around the grammar you are learning. Arrange the words into a reply while hearing each one, then hear the accepted reply and record your own voice. The grammar opens in a side drawer, and recording is optional.
Do I need to finish my deck before starting a conversation?
No. Published chapters are directly playable. Work through your deck and your chosen conversations side by side, at your own pace.
