Usually, the course syllabus is given during the first day of the class. The course description and/or syllabus may be available before the beginning of the class through the Academic Guide. If a syllabus is not available online, contact the academic department offering the course to see if they have a current syllabus.
Please be aware that UC Berkeley considers syllabi to be intellectual property. Instructors are not required to provide a syllabus before the class begins. If you are required to obtain a syllabus before the class starts and one is not available for a course you want to take, you may need to select a different class.
