Which to take? SATII World History VS US History

Hi everyone!

I’m split between choosing subject test world history or US history. I don’t have the time to study both of them, so I have to choose one!
I already took AP world history and got a 5, but was shocked that I got 660 on SATII. For SATII World History, the range seems so broad and specific. For SATII US History, it is specific but it is focused on one country which makes me think of it as easier to study (not that the content itself is easier!)

Have anyone taken both of them or either of them please recommend??

Thanks:)

US History is not a bad test. I assume you must have taken US History at least once before so you are already familiar with some content before even studying

Thanks! How long should I have in mind to study for SATII US history?

If you study regularly for a month, it should be enough.
