Does anyone know of a website that tests / drills grammar?

The only one that I know offhand is the JLPT Study guide but it's still not quite what I'm looking for. (http://www.jlptstudy.com/4/index.html). Then of course there's the minimum of exercises that are attached to Tae Kim's study guide...

To be more specific, I want to drill on い/な　adjectives-- all forms. I get really confused and I think if I was forced into some kind of inane drill, grade school style, I could memorize them by force. (Being forced to memorize that sort of thing is probably the only thing I would get out of studying Japanese in school.)

Then as I learn more grammar, there might be other challenges along the way so it would be nice to have a resource bookmarked.
