I like that you can choose your level or difficulty depending upon how much time one has available for training. You also get immediate feedback as soon as it is provided so there are no surprises! There have been times where we've had issues with our internet connection - but this hasn't really affected us too badly since most training modules aren't very long (so not many pages). It's ideal if someone wants some quick refresher courses rather than going into more in depth topics. We use it mostly when needing short term updates/refreshers such as new software releases which sometimes don't go smoothly. The user interface is very easy to use, which makes it very easy for anyone with little or no experience to learn how to use this tool. I would like to see more courses available for free online, but there are quite a few great ones that are not free. For those who want to learn how to do specific things in Excel, using this software will make the process much easier. I am able to find different tutorials and watch them while my work is being completed by someone else.
