<p>My AP Chemistry Exam has been moved to May 23rd. I just did Chapter 6 (Gases) MCQ in the PR book in 23 minutes. Out of a total of 25 questions, I had 21 correct and 4 wrong. Does anyone have any experience with the 2006-2007 PR book for AP Chemistry? Are the MCQ comparable to AP MCQ's?</p>
<p>I did the first practice book in that book the night before my AP Chem exam, and I found the level of difficulty comparable. Prior to that, I hadn't even done a single MC section for AP Chem, so I thought PR focused too much on calculations in the MC, but that turned out to be spot-on.</p>
<p>PR is great. I didn't take any of the practice tests, but the book was very helpful in some last-minute reviewing (this morning at 4 am...).</p>
<p>I think the PR questions are comparable to the AP questions.</p>
<p>PR is definitely comparable in difficulty with the real thing.</p>
<p>they're fantastic. just right. some of the questions on the AP exam were almost the exact thing with the PR, just with different numbers and elements.</p>
<p>ill let you know after i get my score..lol</p>
<p>Do you guys think FORM B will be somewhat comparable too?</p>
