Mr. D Math

What it is

An online math program founded by teacher Dennis DiNoia, offering courses for grades 5-12 as live classes or self-paced courses. Live students meet weekly with an instructor; self-paced students watch embedded video lessons, work the assignments at their own pace, and can attend two extra help sessions a week. Self-paced access runs until March 1 of the academic year after the one the course was bought for. The publisher states it is accredited by WASC and also offers test prep and some non-math courses.
