<p>Funny story...I haven't started studying for bio at all because I've been so caught up with APUSH, a subject I actually enjoy studying for. </p>
<p>I really don't care about Biology and the score I'll get for the exam. But because I had to pay for it, I just don't want to give up so easily at this point. </p>
<p>Can someone tell me which topics I need to cover? I heard we only need to know the endocrine, digestive, and immune system? Or something like that...</p>
<p>THANKS!</p>
