Free online SAT prep course?

I was wondering if you guys knew of any online SAT prep courses that are in the Udemy, edX, and Coursera type structure. I know Khan Academy is a good resource but it just seems kind of mundane and slow for me… SAT related subjects are good too, I found an edX course on English Grammar and Writing that starts next month, but my reading is especially weak.

Learnerator is nice

I don’t know of any courses offhand, but I know the free SAT questions of the day on the College Board website have been pretty helpful to me.
