<p>I'm currently preparing for Placement Exams including Bio and Chem for CAS. How hard are the exams to everyone? Are they only testing basic/general knowledge or do the go deeper than that, even as hard as AP? I don't want to get caught unprepared, but don't want to over-study for them either. Thanks in advance!</p>
<p>I heard the Spanish one is an SATII. I am not sure if it is the same way for Bio and Chem, though.</p>
<p>chem was one of those california exams.it doesn'tcount though- unless you want to be in accelerated.</p>
