Most vocabulary units teach you between 5 and 10 new words and phrases. Most units contain flashcards with the word, a translation and a key phrase showing the word in a full sentence. If you see a flashcard with a word you already know, great – just move on. If you find a word you don’t know, we advise that you write it down and save it to ‘My Vocabulary’ (you need to be using the busuu website to do this).
You can save a list of all the words you struggle to remember in My Vocabulary, and then at the end of your study session, or when you have a spare five minutes, go into the Vocabulary tab (on web) or My Vocabulary on the app and test yourself on the words. As you become familiar with the words, you can delete them from your vocabulary list.
