<p>Hello, here is my situation.</p>
<p>My school is not offering AP computer science this year, which is a bummer because I was really looking forward to it. My thoughts have since turned to self studying the course. I have A LOT of experience in Java, like, I just got a $250.00 check for some Java freelance work. I picked up a Barron's study guide... but I definitely do not do as well as I think I should... as in I get a 3. I can kill the free response but wither on the MC. I think this stems from having a largely informal knowledge of the subject. </p>
<p>Can someone explain to me how the whole A and AB thing works. Can you take both? Must you take one before the other?</p>
<p>How many hours am I looking at putting in so that I can target my weak areas and score a 5.</p>
<p>Thanks for any input :)</p>
