Beginning with the Fall 2021 class schedule Elon will transition from 3-digit course numbers to 4-digit course numbers (for ex., ENG 110 will be listed as ENG 1100).
Elon has provided a reference document showing all courses offered in Fall 2021 with the “old” 3-digit number and the “new” 4-digit number at the link above.
Remember: The only thing that is changing about the courses is moving the course number from 3 to 4 digits. All other details about the courses (the title, description, prerequisites, where it counts, etc.) remain the same. In the 4-digit number the first digit still indicates the course level.
