Math II Prep Book Recommendations

Hello - my son will be taking the Math II subject test at the end of this school year. He wanted to study over the spring break.

I’ve read a lot of the reviews on Amazon and am still a bit confused on which book to get him. I’ve heard good and bad things about Dr Chung’s book. Also the same regarding Barrons.

I’d appreciate hearing from a student who recently self-studied. Which book was best and why?

Both.
Barron’s to review content and Chung’s to build speed.

Just note that don’t use Barron’s and Chung’s to get a prediction of your score.
They both are way way harder than the real thing.

@YoLolololol thanks! Much appreciated.
