Virtually every problem they have doesn't even have the signs (plus, minus, addition, subtraction). How in the world can someone learn how to solve the problem then they don't even know what the problem is? Some of the content is okay but the explanation is horrible, not many samples. Their website said there was all this free stuff that would come with the packet; however, not one item came with it. In fact, it was just an emailed file, none of the workbooks or special "freebies" came with it. I would not endorse this product. It was a little helpful to know the topics on the test and see what I "may" encounter; however, their study guide is incredibly horrible.
