SAT 2 World History Subject Test Questions

I’m an international student who is planning to take the SAT subject test World History on this coming June which will probably be the last SAT subject test. I learned that there weren’t a single thread about the SAT world history subject test so I thought I would make one since I have some questions.

  1. Since its very hard to find any real tests for subjects tests, where can I find the tests for world history.

  2. Which SAT world history textbook (Barrons, Princeton, Collegeboard, etc) is the best?

  3. Any tips and advice for those who already took the exam.

Thanks, in advance.
