What to review next

Keep a short list of unfamiliar words with their meanings and example sentences. Practise recalling them later, then use them in a sentence of your own.

A focused practice result shows how you did on these tasks. Use several activities across skills to decide what to study next; one practice score does not certify an overall CEFR level.

Before you practise: a worked example

Read the whole sentence before choosing a word. Check both its meaning and the words it naturally combines with.

Please make an appointment before visiting the clinic.

Make an appointment is a natural word combination. Knowing a dictionary meaning alone may not tell you which verb fits.

This teaching example is separate from the scored questions. After your test, compare any mistakes with the explanation and revisit the topic before trying again.
