Is the international SAT always an old US SAT?

I’ve read it somewhere on here, but I just want to know if it’s true.

Yep.

November 2015 (International) was March 2013 if I’m not mistaken. From when was the December 2015 one copied?? And any other instances in recent years of papers being copied??

I’d like to know as well if the international ones are always copied.

All international tests in at least the last five years have been recycled US tests.
