<p>I am planning to take the SAT2 World Hist. in June. However, I am also located in China, and I cannot get any type of review books here. I am currently taking World Hist. in school and I have a great World Hist. text-book. Should I try to crack open the text book and review everything I do not know or is it possible to change the tests I want to take and switch it to US History (Then i can actually have access to materials such as the review book on SparkNotes)? ANY advise would be HELPFUL!</p>
