<p>Hi
My cousin gave me her books: Environmental Science: Earth as a Living Planet the Sixth Edition and Princeton Review: EnvSci 2008 edition and I was wondering if they were current enought to use for this year’s test. </p>
<p>Yes, those should be fine as the test has not changed since then. Many of the recent editions are exact reprints of the older editions, such as PR euro, which has been 464 pages for many years now.</p>
