How it works. Each set teaches ten words from the Academic Word List, the words that appear again and again in textbooks, lectures and reports in every subject. You try five of the words first, meet all ten in a short text, and then practice three things that knowing a word really means: what it means, which form to use, and which words go with it. At the end you meet the first five words again in a new text and see how far you have come. Press the Check button at the end of each part to see why every choice is right or wrong.
