OFFICIAL 2012 AP Computer Science A Thread

<p>So was it 4 E’s or 6 E’s in a row?</p>

<p>How Many points do you think we would lose if we forgot to call super on a certain question…?</p>

<p>1-2^ max but can you answer my question?</p>

<p>I took the AP CS test yesterday, but I didn’t actually take the class; I read the Barron’s book once, about a month ago and haven’t actually programmed in java for more than a year. Oddly enough, I found the test to be pretty simple. Anybody else feel that way?</p>

<p>@prototyped I personally remember getting 4 E’s in a row </p>

<p>Looking forward to tomorrow to make sure my FRQs were correct…</p>

<p>I either got 4 or 5 E’s.</p>

<p>Same I got 4 E’s in a row or 5 I don’t remember right now. I wasted a lot of time rechecking those questions because I thought I got them wrong for sure. Probably wasted about 10 minutes on that. Would have finished with time to spare if I hadn’t done that. Instead I finished with maybe 10 seconds to spare.</p>

<p>So… I kind of took the Comp Sci test without any real preparation. I didn’t take a class for it, and I barely even opened the Barron’s book until the night before the test. I have some C++ experience, so I wasn’t totally in the dark about programming, but I never even wrote a Java program until about 10:30 pm on Monday.</p>

<p>I was okay on the multiple choice; it was mostly just for loops, and I’ve done a lot of those in C++. I guessed on 8 of them, but I was reasonably confident on the other ones. The free response was a totally different story. Fortunately, I had read the chapter on arrays the night before. I used a lot of array coding in terms of variables in my for loops. I was basically lost on the GridWorld question. </p>

<p>I think that I got over 50% overall on the test. Where does that put me on the grading scale? Is 50% passing?</p>

<p>i got 6…</p>

<p>@Kairos</p>

<p>With a 50% you maybe got a 3 or 2 depending on the curve. If you are extremely extremely lucky maybe a 4.</p>

<p>FRQs have been posted. Talk away …</p>

<p>@jkhuggins once you look at the questions more carefully can you tell me how many points I would lose if I called restore in the act method?</p>

<p>For the two questions where you answer yes or no I put yes for both. Was that right?</p>

<p>I think the first one was ‘No’ because the method only stored the name before the one you were currently checking. You could not guarantee that the method would accurately check for duplicates because the list was not in order.</p>

<p>Just finished taking the exam myself, so I can offer my opinions …</p>

<p>@steve1sterling: really not sure. It all depends on the rubric. At a minimum, it’s at least a full point deduction from the general scoring guidelines for a destructive side effect, assuming that your restore code actually works. But I could see it being a bigger penalty, depending on how much of the rubric focuses on ensuring that act() still works correctly. Sorry I can’t be more specific.</p>

<p>@techhexium: like @Ronaldofan94, I think the first one is No, and the second is Yes.</p>

<p>Whats the curve?</p>

<p>Curve won’t be known until all the scoring is done. Sometimes, it’s hard to predict whether or not a given problem will score high or low.</p>

<p>For RetroBug, I did a test to move it back to its original Location, if the previous Location had an Actor that was null or a flower. However, if the bug had only turned and not moved, the Location would return the Actor (the current bug), so the bug would not restore as it failed the test as the Location had the bug in it. What would be an estimate of points lost for this?</p>

<p>Completely guessing here … maybe a full point. Your bug did restore to its proper location all the time (note that not restoring when you didn’t move still leaves the bug where it belongs), and restores direction some of the time.</p>

<p>Alright, thank you.</p>
