## Electronic Homework Pages-CSUDH Chemistry Department

This is the entry point to a set of pages for the performance and submission of homework
assignments using the World Wide Web. The active pages have a star in front of them. To reach a page, click on the in front of the title. Your instructor will have given you both a title and a page number. Make certain that you are doing the correct page before beginning. If you are new to this system, it is recommended that you orient yourself to its operation by loading the first page, "Significant Figures", performing one problem and submitting the results. These pages have been revised and should run under Netscape 3.x or 4.x and Internet Explorer 4.x. It is strongly recommended, however, that you use **Netscape 4.x**, if possible. It has consistently provided the best performance with these applications. There are some pages which will only run on Netscape. These are noted with a **Netscape Only** tag. Feel free to let us know of any problems by using the the email link at the bottom of this page or any of the homework pages.
