<p>um, i have an AP BIO book but im wondering if i should buy an updated sat2 bio book?
im taking bio for sat2 but im not sure if studying from my last years (AP) bio book would help with the (sat)2? (since it is pretty diff from the two)
or should i get/check out the actual sat2 books?
i think that will work, but i wasnt sure, since it e/m and all.</p>
<p>please answer if ur sure! thanks</p>
