I am not sure if these have been shared before and how are they compared to the more reputable online Math courses...but they are free! http://www.montereyinstitute.org/courses/Algebra%20IA/nroc%20prototype%20files/coursestartc.html
DS8 worked on this for the past 2 days since we are are stuck at home with typhoon. He didn't go through the lessons but went straight to try out the "Lesson Practise Test" under the Multimedia Play Lesson. He could "submit" his completed test to chk his answer immediately on his own.

There are more free courses from :- http://www.hoagiesgifted.org/online_hs.htm smile
