ACT International Testing for UC

So I’m taking the ACT in December. I was scheduled for it in October but it was shifted to December after my Mother got into an accident. It is the international CBT. Will it affect my application if the international CBT ACT is taken in December? Also, how is the international ACT? Is it difficult to navigate? Do people score lower in it? If anyone knows anything about either of the topics above, do let me know. Thank you.
