ESL/IEI: English Grammar Exercises

http://www.englisch-hilfen.de/en/index.htm Learning English Online

This is a German site, but is a great source for English grammar explanations and exercises. The English Forum is in German, so you may not want to go there unless you speak German. The quizzes are in English, and students can enter and score their results online. They are also designated as 'easy' or 'medium'. There is quite a comprehensive list of grammar subject areas to review, as well as explanations. Students can take more comprehensive tests ('complex') or even practice English with games such as Hangman or Find the Pairs.
