How can I add/change/cancel my college choices or correct my high school code after I register?
If you registered for national or international testing*, you have until Thursday noon, central time, immediately following the regularly scheduled Saturday test date to correct your high school code and/or add/change/cancel college codes. The same deadline applies even if your test center is rescheduled for any reason (e.g., inclement weather).
The best way is to log in to your ACT Web account and select "Make changes to your registration." There is no fee for changes to the first four college codes. After the deadline, all changes must be made by requesting and paying for Additional Score Reports.
8:00 a.m. to 8:00 p.m., central time
