APCS A Pre Exam Tips

<p>Hey I understand that this is a bit late but I'm in need of help. I have my APCS A exam tomorrow morning. I'm order to receive any credits for the class I need to get at least a 3 on the AP exam. (It's an online course at my school so the AP is how they judge if you actually learned). My problem is that the online course has taught me very little about Computer Science and I do not feel confident. I have basic understanding of loops arrays and grid world (enough to get around to get around a 25 on multiple choice section). However, I'm having an insanely difficult time answering the open ended questions. Is there anything I can do to get half credit on these? Any strategies? I hear that if you attempt a loop and call the methods you can get partial credit.
TLDR=I need some tips before the exam on how to get some credit for the open ended section.</p>
