I've changed my mind about taking the ACT writing test. Can I add or remove this test option?
Yes. Log in to your ACT Web account and select "Make changes to your registration" no later than the late registration deadline for your test date. Fee adjustments depend on whether you are adding or removing the writing test and whether other services are required to find you a seat (for example, a Test Center Change).
If you change your mind after the late deadline, you may attempt to change your test option on the day of the test. Tell the test coordinator at your test center that you want to change your Test Option before you are admitted to test. If there are materials, space, and staff available for your preferred test option, you will be allowed to make the change. If you change to the ACT with writing, ACT will bill you for the additional fee.
See current ACT fees for specific information.
