Yep - the vocabulary lists really helped me in my exams

and the 11 plus playing cards are great for boosting your vocabulary as well.
However, in order to increase the range of your vocabulary further, you need to act for yourself. Whenever you see an unknown word in a book, newspaper article, etc., look it up in a dictionary and add it to your very own vocabulary list. Whenever you finish a test paper, go over it and look up all the words you don't know and add them to your list. Remember to ALWAYS have a good dictionary and thesaurus nearby.
In addition to that, Check out the Vocabulary Booster course found in the
Online Testing area of this website. Take each test multiple times as each time you will get a different set of words.
I hope you have fun increasing your vocabulary!!
