It's up to faculty to decide when to make their CoursePlus sites available to students. Some faculty choose not to do so until the first day of the class. You can always see a limited amount of information about the course by visiting the list of all courses in CoursePlus and finding the relevant class there. The syllabus and schedule pages are always publicly available. If you need more information, you can reach out to the course faculty. Again, though it's up to them to decide when to open their course sites. CTL Help cannot make the site available for you.
