<p>I understand that PR is better, but my teacher uses Barron's and we use it in class so I kind of need to use it. I hear it has a lot of mistakes, but is it that bad? PLease let me know</p>
<p>All I know is that it is very lengthy and the questions are more difficult than the real exam.</p>
<p>Barron’s has lots of typos and occasionally more serious mistakes, but the environmental science prep book didn’t seem too bad. I self-studied using Barron’s and nothing else, and got a 4. (Of course, maybe an opinion from someone who got a 5 would be better.
