Some of the initial material on this site is rather elementary, and probably already known by people who are not newcomers to the Internet. The questions also tend to be elementary, although some require critical thinking. A few questions may require specialized knowledge that may be too detailed for most users (e.g. a reference to the periodic table).The introductory material may be a bit more verbose than necessary.The site is on a server in Great Britain, and some of the examples and content relate to that country. This may be useful in exposing students in other countries to different perspectives.The site has a very extensive bibliography at the end, but it appears that the most recent print items date back to 1996.Technical Remarks:This tutorial can also be downloaded and used off-line. This may be helpful for times the connections to the server in Britain are slow.The user who enters a username at the start can stop part way through the tutorial. The scores for the previously completed quizzes will be retained for when the user returns.The site has several navigation options. At the bottom of the screen are Prev, Home, and Next buttons. The links on the left side of the screen can be used to go through the material nonsequentially. However the way the links expand may be confusing to some users initially. Also there are links at the bottom of the central frame at the end of each module that lead to the next module.
