<p>My friend was telling me about the SAT biology subject test and that's shes taking it after the AP test... do most people do this? Is it good to do?</p>
<p>well you’re already prepared since you just took the ap. some people use the subject test to prepare for the ap (thats what i did) while others use the ap to prepare for the subject test. it doesn’t really matter as long as you know all the information!</p>
