Chemistry- PR vs Sparknotes vs Barrons

<p>I'm taking the Chem Subject Test in October, and after reading the suggested book list thread I bought the Barrons book and the PR book, with the former being for info. and the latter being for practice tests. Both, from what I read, have their shortcomings in the info. department, with Barron's containing excessive information and PR lacking some. From those who have taken the chem test before, what extra info. does Barron's have and what does PR lack? Is Sparknotes superior to both of these for information? Thanks for your help.</p>
