DD did AP Global and got a 4. She was scheduled to take the SAT 11 in Chem and Math 1 (she has done geometry, Algebra and trig) in August but I don’t think she is ready for that so I want to switch to the World History instead of Chem. What is the best prep book for SAT 11 World History? Barrons got a lot of bad reviews on Amazon for that particular subject? We have Barrons for the Math.
