How practice and review work.
You see what you answered independently, what needed help, and when to try it again.
Two ways to practice
In dictation, listen and type the complete sentence. Nothing is marked right or wrong before you submit. In phrase recall, use the sentence and meaning to type a missing expression. Both use a real text input and work without a countdown.
How answers are checked
Letter case, extra spaces, and final punctuation do not affect correctness. Contractions, spelling variants, and alternative phrases are accepted only when the question explicitly includes them. Send and sent are different forms.
A reasonable alternative can be accepted without crediting the target expression. For example, free can fit “She is ____ on Friday,” but it does not demonstrate recall of available.
First try, help, and replay
Your first answer is recorded separately. Retrying or using a written hint cannot turn that first answer into an independent success. Listening again is allowed and is counted separately. A revealed answer can be typed again or used to continue.
Review timing
Initial review intervals are 1, 3, 7, 14, and 30 days. Due expressions advance after an independent correct answer in a later session. Mistakes return sooner. Early practice updates the last exposure time and does not advance the interval.
Dates and results
Daily questions use a fixed UTC date and content version. A session keeps those questions after midnight. Your personal streak uses the time zone saved when each session starts. Personal reviews do not change the daily result.
How content is checked
This preview includes 60 original draft units and 120 generated recordings. Before course publication, each unit needs text review, audio listening checks, documented source rights, and approval. Automated checks can catch missing files and answers; they do not certify natural English or teaching quality.
What the results mean
Results describe performance on these exercises. They are not a language proficiency test, a CEFR certification, or a measure of words permanently learned.
