SAT Biology Subject Test prep book from 2001?

<p>I bought my AP biology materials from a previous student and she also gave me a supplement book for the SAT Biology Subject Test. However, the Sparknotes supplement book was published in 2001. Has the format and content of the test changed that the book won't help at all?</p>

even though I tend to buy prep books from previous years (bc they are much cheaper) I would say books from 2001 are little bit outdated… the test has probably changed a lot… even though basic concepts are probably the same…
I would recommend buying a more recent review book

I would pick up another book, preferably one from 2011 (when the newest book of practice tests was released) or later.
