<p>If you haven’t started anything on objects thus far you definitely have a lot to catch up on – it’s doable but very difficult to master in the amount of time you have left (assuming you are new to programming – if you had taken a programming course before you should have already covered the basics so your AP course could have started with object oriented stuff). But good luck regardless!</p>
<p>Also as a general tip for a 5 – get Litvin’s “Be Prepared for the AP Computer Science Exam in Java”. It’s a big help and has clear explanations.</p>
