<p>ok so I'm just using Princeton review for AP calculus AB and i reviewed up till chapter 8 by tomorrow afternoon I'll complete the whole book and then take the 2 practice tests in the back is that sufficient, or should i do more practivce tests from other books I'm aiming for a 4/5</p>
<p>also how accurate are the PR tests compared to the real ones are they easier or harder?????????</p>
<p>The PR is generally an accurate representation of the AP test. But that doesn't mean its absolutely 100% dependable. I would look at the released versions of the real free responses on the AP website.</p>
<p>I did the Barrons practice tests and in a mock exam (using a previous actual exam) scored well above what is required for a 5...Barrons is ridiculously hard, much harder than the average questions you will come across on the exam for the most part anyway IMO. I am not worrying too much but I guess just briefly skim over the past FR questions, because the questions are more likely than not going to be very similar to those. As for MC, it's just practice and pacing.</p>
