If you are looking for a simple online program for studying vocabulary, consider using Word Dynamo, a free service offered through dictionary.com. This program lets you study vocabulary by grade, by test (SAT, etc.), by subject, and by language. You can even create your own word lists for personal study as well as your own personalized home page for tracking your progress. I gave the program a quick try and got a word score of 50,052. Give it a try and see how high you score!
