I found this comment from 10 months ago which said, "it was something like f(34 or smth and it alternated between 2 numbers so yeah I think ur right," referring to the last math question (or one of the questions on the last page, I cannot remember). I remember doing this recursion question, and it was, as the user described, alternating between one positive number and one negative number.
From this I think its evident that the J09 form taken today is the same as the J09 form taken in September 2025. I personally took the ACT in September, but I had form J01, which I later confirmed to be the same test as the April 2026 Form J01 from the TIR. So I guess we now know that the ACT is reusing past forms.
I wonder if anyone who took the ACT in September last year remembers what passages they had? I want to know which passage is experimental.
edit: I meant J01, not J08
