Best review book for Math II SAT Subject Test?

I'm looking for some helpful study resources for the Math II subject test. Which review book should I get?

I'd recommend the Barron's review book for Math II, supplemented with the official College Board review book for extra practice questions. Although some people have reported a few errors in the Barron's book, it seems to be a helpful resource overall. The material is also pretty challenging, so you'll be extra prepared for the test. The College Board book doesn't have as much in the way of content review, but it's a good source of practice tests and questions that are a reliable representation of what you'll see on the test.
