This book contains a series of tests on those words an intermediate student should know,and some other words we think he might like to now.There are tests on synonyms,opposites,health,sports,school,the mass media and so on.These tests should be done once,and then be corrected.After a few days,they can be taken again.This way the student will reinforce what he learns,and fix it his mind so he can use it actively when the need arises.Finally,at the end of the book there is a final test which covers many of the words of the first part of the book.Good luck!
