In our extensive vocabulary tutorials, students not only memorise a wide range of vocabulary but are accustomed to the full and appropriate usage of each word, that it becomes fully a part of their own dictionary. This is what we call mastery. In order to achieve this word mastery, students participate in a myriad of carefully constructed vocabulary activities that strengthen their judgement of when and where to appropriately use the newly learned words, and to improve their spelling, grammatical and punctuation skills.
