Changing ACT (No Writing) to Writing?

<p>Am I allowed to change from no writing to writing? Can someone show me how? </p>

<p>Thanks</p>

<p>After taking it or before?</p>

<p>I believe you can do it at your test center. You’ll just be billed later on.</p>

<p>Change at the test center. There is no fee that way, you get a message in your account online that makes you pay just the $15.50 more the writing costs before you see your scores. They usually have plenty of extra writing sections.</p>
