I would like to ask what are the goals of online university classes. I have just helped a friend to prepare for the paper she has to submit this week. The topic regards the comparison between two different table which have to be prepared by the student using two different softwares. After we spent some time understanding how the table should look like and which data we can use, we realized that we only had one of the required softwares available and no idea of how to get the other for free. We checked the book, the website, the class description and nowhere was to be found a link or a hint of how to get the necessary software.
