<p>Please don't bother with Kaplan because their tests are absolutely inaccurate and contain superflous information which is not needed on the exam. The Barron's and Sparknotes are also terrible, but better than Kaplan in my opinion.</p>
<p>I found Sparknotes’ scoring to be terrible, but the content in them was VERY close to that in the real test. Kaplan was also helpful, but it did have some superfluous stuff.</p>
<p>Princeton Review: 680, 780, 720
Sparknotes: 620, 680, 650
College Board Practice Test: 730</p>
<p>my scores
princeton review: 750,770,680
Sparknnotes: 550,570,still have to take third
Collegeboard:750 from the 1998 edition book, and 750 from the new edition.</p>
<p>Real thing: A Columbia hopeful hoping for a 780+</p>
<p>just finished taking the last sparknotes test and scored a 540… 590 if you don’t don’t count the penalty for wrong answers. Well I’m just gonna have to force myself to go over all my mistakes despite this discouraging score</p>
<p>Kaplan books, in my opinion, are not so great to use for practice tests. I have always found that their practice tests do not really match the content of the test (for both SAT chemistry and the SAT) and some questions were not worded clearly. I scored significantly lower on them than I did on the real tests. However, they do provide helpful information. For chemistry, I liked the Princeton review for the practice tests. They were a good predictor of my score.</p>
<p>PR: 680
Sparknotes: In the mid-500s
Barrons: 650-700
Real Thing: 650
I’m not sure if this can be counted as completely accurate because I didn’t get to really study before the first time I took it.</p>
<p>Princeton Review: 700, 630
McGraw Hill: 670
Sparknotes: 490 (their tests are horrible)
Barron’s: 650, 670 (night before the real test)</p>
<p>REAL: 750</p>
<p>I highly recommend Barron’s. They explain everything so thoroughly, and even though people say it’s harder than other books, it’s still relatively simple (especially if you’re in AP Chem).</p>
