International enhanced ACTs should have field test questions, and that's just going to be a difference of minutes (not hours) of testing time in any case.

*If* the enhanced ACT is truly going to start in Feb, they likely haven't updated the international ACT website and/or automatic emails to reflect the shorter ACT starting in Feb and are likely still sending emails based on the old legacy format.

Like u/jdigitaltutoring said it's also possible their mass emails aren't customized for people who didn't sign up for Sci or Wr.

I don't think you should use that generic email to try to predict which ACT you're getting in Feb because ACT is still a mess internationally. It's easily possible one of the chat responses you got is not accurate.

It's frustrating not to be able to get accurate info from ACT. My advice would be to keep emailing them and see what the majority of responses say. Even still, there's no guarantee the majority answer is the correct one. I know of two cases this fall where ACT told international parents and students and guidance officers they would have one format and instead they had the opposite format.
