The section "review" is where you can practice all the words you have learned with busuu.
You can decide to review all your words, only your favourite words (you need to mark them as favourite by clicking on the yellow star), or your weak words (Strengthen vocabulary).
Weak words are defined by an algorithm and are the words you struggle with, have encountered less often, or not seen for a little while.
It helps you stay on top of things as you progress throughout the course!
Note that you can only review your words if you have enough of them in your list (minimum 5 words listed). Also note that you can only play your favourite words from your mobile, not from our website.
