Usually, the course syllabus is sent to students during the first day of the class. The course description and/or syllabus may be available prior to the beginning of the class through the Class Schedule. Sometimes you may be able to find an old version by looking it up. If a syllabus is not available, however, contact the department offering the course to see if they have a current syllabus. There are no guarantees that they may have something available but there is no harm in trying!
