Thank you!

Last year I only started reviewing for the exam two weeks before. I used Princeton Review and I ended up getting a 5. I guess it might not be everyone’s cup of tea, but the conversational style of the book was really helpful for me. I also found that they included just the details I needed for the exam. If you can, I would also recommend the SAT Subject Test for US History.
