SAT II Math II Book

<p>I am looking to take the Math II test this June, and given that my sibling has already taken the test, I received her old books. I have a Barron's 2008 and a College Board (Math I & II) 2006. I have three questions for anyone who has knowledge in the area:
1. Has the Math II test changed over the last 3-5 years?
2. Do the books I have cover the material if the test has changed?
3. If the books are not good enough for the test, could you recommend a book?</p>
