<p>I’ve reviewed Barrons and on the practice tests i always seem to get atleast 20 wrong. I’m even in AP Chem and I get a B+ in the class.</p>
<p>I havn’t started PR but I plan on…what should I do to bring down my mistakes…i want atleast a 750…</p>
<p>Just practice and study? Try to make sure you fully understand concepts; that is, don’t just memorize a technique that you were shown, but understand why that technique works.
Anyway, I’m not a fan of Barrons, you should use PR and just stick with PR.</p>
