I used learningext.com...I purchased the 3 week course for fifty dollars. I loved it. Very nice program! I had several SATA, so many I lost count honestly. I had a few drag/drop, a lot of meds and no math. I don't like that I didn't have any math, it actually makes me nervous! But it was definitely nerve racking. So my advice would be every time you start to get anxious, close your eyes and breathe! I did that a lot!!
