<p>I am the tutor of my son. I want to know that Real SAT2 chemistry test is harder than practice tests of barron or Princeton Review?
thank you.</p>
<p>no, its more like the barron's one. in terms of difficulty, i'd say PR, but a lot of the material that is not covered in PR is covered in barron's - i.e. there were random problems about the ozone and fertilizer (the ID problems, which are usually easy, were pretty hard and unexpected) that were apparently in the barron's SAT II chem book. So if you read through the entire book, I'd say you're guaranteed an 800 (if you have a good chem background). If not, depending on how much chemistry you've taken, definitely over 700. </p>
<p>I'd take the Barron's practice tests; if you score over 750 on them you should be set for the SAT II.</p>
<p>Thank you ebonyear for your message. It is much help to me.</p>
