AP Biology

<p>Are there any things on the test that students don’t seem to know? I remember some kids from my school saying that they didn’t know too much about insulin/glucagon and calcitonin/PTH feedback loops, so I studied those sorts of things in more detail.</p>

<p>Also, how much pure vocabulary recall is required for the test (ie differences between allopatric/sympatric speciation and other specific words)? I seem to have a good grasp on concepts, but my pure vocabulary may be lacking. Any suggestions?</p>
