A careful Web search will turn up many academic tools and resources from highly regarded colleges and universities all over the world. Don't be shy about using them. Below is a compilation of course-related material from around the Web for use by Colorado State University students.
Just remember, the resources on these sites were designed for specific courses at other universities, and may be slightly different than the content in your courses at CSU.
When studying, always cross-reference these and other web resources with your own class materials, notes and textbooks. If in doubt about the usefulness of a web resource, ask your professor.
