SAT USH WHAT TO DO ????

Hi all,
thanks partly to college confidential, i got a 2400 super score on the old sat.
I am now preparing for sat us history.However, as an international, i dont know much about how to prepare for sat us history :<<
How can I best prepare for the test? any book suggestion ? any study methods and tips?
Do you guys just memorize the whole prep book or st? If so, then which prep book is the best option?
thanks thanks thanks =))) please share your opinions.

I took SAT II USH last year after taking the APUSH test/class and watched Adam Norris videos to review. I’ve heard positive things about the Barron’s prep book from friends, and supposedly Princeton Review and Kaplan are both good too. I thought that the test wasn’t particularly hard, so I wouldn’t stress about it too much.

thanks @dr0wning but iam stressed out about it as memorising hundreds of pages does seem intimidating :<
but i do hear that sat ush does not test certain things like battle. Uwhat exactly does it test and what it doesnt ask ?
