This program is generally helpful. I mostly gave it three stars because it over-explains the concept, which is an amazing problem to have. Occasionally there is, however, no correct answer on multiple choice tests. As far as helping me understand concepts goes, Savvas Realize is a good program. Unfortunately, the bads outweigh the goods at times.
Wow. I am absolutely blown away by how useful this is. Many times, I'll go out of trig class wondering what just happened, and go to my delta math assignment. I look at it and instantly get worried, knowing there is no way I'll be able to solve the problem on my own. But delta math apparently remembers what it's like to be a kid, and provides a number of help videos and question examples. Not once have I gone out of a delta math assignment still not understanding a concept.
