<p>Here is the official collegeboard breakdown of the exam:
[AP:</a> Biology](<a href=“College Board - SAT, AP, College Search and Admission Tools”>AP Biology – AP Students | College Board)</p>
<p>Structures and functions of plants and animals is 32% of the test, so if I were crash-studying, I’d focus on that! Homologous structures and all that fun stuff.</p>
