What is the difference between "Edit Selection" and "Reset Selection"?

Use "Edit Selection" to:

Change from "Plan to Enroll" to "Commit to Enroll" at the same school (e.g., you currently have Plan to Enroll" selected at Medical School A and want to change it to "Commit to Enroll" at Medical School A). *Note: you can begin selecting "Commit to Enroll" beginning April 30.

Change your "Plan to Enroll" or "Commit to Enroll" selection from one school to another school (e.g., "Plan to Enroll" is currently selected for Medical School A, but you want to change your
"Plan to Enroll" selection to Medical School B).
