Can someone who has used Wordsmart give me a review?

I was watching the Wordsmart infomercial with Alex Trebek on it and afterwards, felt like wanting to but it. When I usually see infomercials, I skip them. After watching, it seems as though the program could drastically help me improve reading and comprehension, therefore help my chances of being accepted into a prestigious university. Can someone who has used Wordsmart give me a full review and tell me whether or not I should buy it?
