<p>I know it's way too early for this, but considering the new exam format I think I need some time to prepare. Which book helped the most in the new format? </p>
<p>Just use Bozeman science/khan academy videos. Briefly used PR but found it lacking. Also get official practice exams, they’re invaluable for learning the new format. Got a 5 last year doing this. </p>
<p>Barron’s is great for AP Chemistry.</p>
