If your students can master all of the vocabulary words in Charles Harrington Elster's book Verbal Advantage: 10 Easy Steps to a Powerful Vocabulary, then they will be at the vocabulary level of the top 5% of educated adults.
This book is a great way to teach vocabulary in my AP class. They were not challenged by the SAT vocabulary prep books, and this was the one book I could find that was actually a challenge for them.
The book is divided into 10 lessons, each composed of 50 words. There are three quizzes per unit--words 1-15, 16-30, and 31-50. The quizzes in this download are for Lessons 1-5 for a total of 15 vocabulary quizzes.
To use these quizzes, you will have to purchase the book. The quizzes do not contain a word list.
Here is a PDF copy of the book:
