Changing Writing Form on the Test Day?

Hi everyone!

So I took the ACT today.
The instructor said that he received an email from ACT that said that the intended writing booklet form (32G) had to be substituted to another one (32N). He printed it on paper and handed out with the original booklet.

Does anybody know why would they do that? I’m just curious, nothing else.

Where did you take it? It’s probably because the previous form (32G) had been leaked. @summr99T
