Placeholders are handy for when you know you need to fill a requirement, but you’re not sure yet which specific course you want to take. You can hold a spot in your term for the requirement you want and choose between available courses later.
You can add a placeholder by dragging a requirement from the degree requirements sidebar.
You can also add a placeholder by clicking on the "Add to term" button in the term you want to select, then searching for a specific requirement.
Placeholders will be shown with a dotted outline, and clicking the placeholder box will show all courses that would fill that requirement in the sidebar. Once you have decided on a course to use for the placeholder, you can drag a course into your plan which will then replace the placeholder. The course then shows with a solid line instead of the dotted line designating a placeholder.
