*** Official AP Computer Science A Thread 2013-2014 ***

<p>And in terms of practice tests are Barron’s practice tests accurate or should I do the practice test pf Computer Science A for 2008. Since the CS AB was discontinued in 2009 will the 2008 practice test for CS A be inaccurate.</p>

<p>anyone take the late-testing exam today?</p>

<p>I did. The grid world frq and the second part of the archeological question killed me. In general, the mc were ok. What do you think the curve will be like?</p>

<p>@blizzardsnorth Be careful; you’re not allowed to discuss the details of any of the FRQs on the late-testing exam, because they may re-use those questions in future years. Usually, though, the curve on the late exam isn’t that much different from the curve on the regular exams.</p>

<p>@shijurodhaz The Barron’s exam for CS-A should be fine; the only major thing that’s changed since CS-AB was eliminated was that 2D arrays are now a part of CS-A. (Also, starting next year, no GridWorld questions on either part of the exam.)</p>

<p>@blizzardsnorth‌ Same here. The very last part took me a good 15 minutes…</p>

<p>MC was ok. Free response was so easy that I drew many pictures, including a beautiful flower with glossy petals.</p>

<p>@blizzardsnorth‌ I also thought the Grid World was hard.</p>

<p>Also there was a question covering the topic of binary and decimal. All I can is I found the answer to life, the universe, and everything.</p>

<p>@pizzabagel‌ Agreed. Perhaps collegeboard is trying to tell us something.</p>

<p>I thought MC was like med, and FRQ super easy. true, the last part took longer than the others, but I got it after some thinking. </p>

<p>lol binary to decimal, that was a surprise. I also wasn’t fully prepared for all the searching and sorting questions, but it wasn’t a huge deal.</p>

<p>Yeah was the answer to binary 42 or 84?? there was that 2 subscript and i went what. And what question number was that??</p>

<p>Oh wait jk that just meant base 2 nvm</p>

<p>I felt that towards the end the questions kept getting longer and more annoying…</p>

<p>:( I took it, by the end of the first 75 min I still had like 2-3 multiple choice at the end remaining that I had to guess on, but other than that it wasn’t too bad. Free response was probably one of the more difficult I’ve seen just because of the amount of reasoning in like… all except the first question. But the excess amount of time helped.</p>

<p>Yeah for the 2nd part of the 1st question did you have to make a constructor? I wasn’t sure…</p>

<p>@‌ Pikafruit almost same the multi was really easy but long enough that I had to fill in b for two problems, the free I found pretty easy except for the gridworld question(was it (overriding getMoveLocations()???)). Otherwise Im pretty sure Ill get a 5.</p>

<p>@luckyducky101‌ I agree. I finished the first 20 questions in 20 minutes, but for Grid World I spent about 10 minutes and then I spent the remaining 45 minutes on the last 15 questions.</p>

<p>@yoyo27‌ I overrided selectMoveLocation and makeMove, but now that I think about it it would make more sense to modify getMoveLocations and makeMove. (makeMove needs to be modified since the critter only moves if the location to squares behind it is empty and valid, where a normal critter removes itself from the grid if the location is invalid.)</p>

<p>Yah mine was similar except shouldn’t it be value>3 since 60% it moves normally? </p>

<p>@luckyducky101‌ Yeah that’s right. I couldn’t remember which percent went with which behavior.</p>

<p>yeahhh that’s pretty much how i did it except i used a for loop which was longer lol</p>

<p>I’m so glad to see that other people thought the MC was painful too! I self-studied off of the Barron’s book and learned all those different coding organization concepts, sorting algorithms, etc. but NONE of that was on the test. So much recursion… O.o</p>

<p>The FRQ section was really easy, though. Besides a few mistakes in the first question (forgot to deal with some special cases), I think I got most of them correct.</p>
