<p>i put 15/5 looking at the bounds on the for loops</p>
<p>when can we see the free response questions and solutions?
(when will they come out on the website)?
also, what did you get for question 3, the one about A and B classes</p>
<p>In regards to GridWorld, does anyone know if you can create your own locations and test them against a grid’s locations? Or can you not because that’s just not legal.</p>
<p>You can honestly do whatever you want as long as it a)doesn’t say to use a specific technique and b) doesn’t forbid it in directions/post-conditions.</p>
<p>
</p>
<p>The answer should be B, since they said ‘A obj = new B();’</p>
<p>
</p>
<p>I’m not quite sure what you mean, but what I did was used a double nested for loop with rows/cols, made a loc object for each (row,col) and checked if get(loc) was null. So, the answer should be yes.</p>
<p>@rierro Yeah, that was what I meant. I spent like 20 minutes on the question pertaining to that wondering if that was the solution… just decided to write it down anyway, awesome.</p>
<p>Did any of you get OutOfBoundsException thrown for one of the recursion MC?</p>
<p>This thread is becoming ridiculous. Did ANY of you guys pay attention during the security statements? There are MCQs being freely disclosed in this thread (which is completely against policy) and the details of the FRQs are being discussed early as wall.</p>
<p>Here’s the CB policy. It’s not rocket science; if you could take an AP CS test I’m sure you can understand it:</p>
<hr>
<p>The College Board will automatically cancel your exam score if you are discovered disclosing:</p>
<ul>
<li> multiple-choice questions;</li>
<li> free-response questions from an alternate exam;</li>
<li> free-response questions from a regularly scheduled exam within two days of its administration; or</li>
<li> free-response questions that are not released on the College Board website two days after the regularly scheduled exam administration.</li>
</ul>
<p>This means that something you may not have intended as a violation, like casually talking about a multiple-choice question with your friends or your teacher during the exam break, or discussing a free-response online right after the exam, can actually result in having your score canceled.</p>
<h2>You can only discuss free-response questions from a regularly scheduled exam after two days have passed, and if that particular free-response question was released on the College Board website.</h2>
<p>You all need to edit your posts and remove the information until the FRQs are released (and the MCQ information permanently).</p>
<p>@Mentonin</p>
<p>Somebody’s mad because they’re finding out all their answers were wrong ;)</p>
<p>@Nidget yep that’s what I got, I don’t remember exactly but I know the base case did not prevent attempts to use out of bounds subscripts or something.</p>
<p>Not to act like a rebel, but how does Collegeboard know whose scores to cancel when they only have the info of a user on a discussion forum? Either way, I haven’t discussed FRQ or MC yet with anyone and I plan to keep it like that ^.^</p>
<p>@Nidget, not to disclose MCQs , but bubble sort is not tested by the AP. You probably confused the sort with sequential sort since the two are easy to confuse.</p>
<p>Also, theoretically, can a helper method in the same class be called in the constructor to instantiate an instance variable?</p>
<p>does anyone have the answers to the 2008 ap exam?</p>
<p>@FlyingWombat I see no reason as to why not, a constructor can indeed call a helper method.</p>
<p>@DaneBrick </p>
<p>I’m not sure about the MCQs, but FRQs are here: [AP</a> Central - The AP Computer Science A Exam](<a href=“AP Computer Science A Exam – AP Central | College Board”>AP Computer Science A Exam – AP Central | College Board)</p>
<p>My teacher just gave us the MCQ answers</p>
<p>@FlyingWombat that’s correct; the important thing to note in terms of subclasses is that they do not have direct access to private instance fields of the superclass.</p>
<p>Hmm I was under the impression that since instance variables are inherited, instance fields that are inherited can be directly modified by a subclass since it belongs to the class. I thought that the visibility modifier only changed visibility by a client class? (I think I’m probably wrong)</p>
<p>Yeah I looked that one up after the test and according to Barron’s private instance fields of the superclass can only be accessed from the subclass via accessor/mutator methods.</p>
<p>Wow, I did bad on the multiple choice (I had to guess on 1 question cause I didn’t have time to finish). At the worst I got ~33. As for free-response…it was so easy for me. I actually took my time to read the instructions carefully, but I ended up taking a nap for an hour after I finished.</p>
<p>Hey I self-studied for APCS and I think I did well. However, I really have no idea as to the degree of strictness used in the FRQ grading. I walked out of the room thinking I answered 4 questions near perfectly, but I’m sure I made some careless mistakes. Could any of you who had a teacher or other knowledgeable source shed light on this topic? I.e. if I wrote code that works and answers the question, but perhaps has some problems (more severe than simply minor errors), will the graders find ways to take off a lot of points?</p>
<p>I think I got 30-35 or so on MC and I didn’t really have any problems on the FRQ’s other than what I discussed above. Do you think I could get a 5? I really have no idea so any help would be appreciated.</p>
