*** Official AP Computer Science A Thread 2014-2015 ***

The MC was not that bad but question 3 and 4 on FRQ was hard.

The MC was gross. I just realized I forgot to write getter and setter methods on the FRQs. Are getter and setter methods required if they aren’t used for other parts of the question?

No, they are not required as far as I know. I had trouble understanding what one of the FRQs was asking

GOD BLESS AMERICA. Oh yeah one of the FRQs I just stared at and had no idea what I was supposed to be doing for like 10 minutes.

MC was a little difficult, did not have any time to check and I was unsure of many.
FRQ the first two were pretty easy, then I’m pretty sure I messed up the last two. Like I had no idea what they even were asking. Last FRQ was so bad holy.
@ypmagic What’s the Comp Sci curve? Is it really that bad?

last frq killed me

Guys, about how many points would I lose on the FRQ if I forgot to account for the array list size changing when I removed it… I can’t study for APUSH thinking about this mistake… :frowning:

@Defeat like one

@ypmagic I think for the last FRQ, instead of using a current method I already created, I just wrote it all over again basically. How many points do you get docked off for those kind of mistakes?

Does anyone know how many points you lose on frq if you write too much code? For one of them I answered the question with my code but I also wrote something extra that’s wrong from a coding perspective. Can I expect to lose just a couple of points or a lot for that?

I think I saw one of the scoring guidelines say that extra, unnecessary code is not penalized unless it interferes with the functionality of the program, in which case it may cause you to lose one or two points

@Potter16 I was reviewing old FRQ Scoring Guidelines, and generally the rule is “if the student writes extraneous code that has no side effect” there is no penalty, but if “the student writes long amounts of code to complete a task that could have been achieved by a simple call to a method” (paraphrased) you do get a penalty (-1).

I want to start this with a standard disclaimer: I’m an AP Computer Science reader and have been for many years. I’m happy to contribute to this discussion. But everyone should know that my opinions here are just my own; they don’t necessarily reflect the opinions of the CollegeBoard, ETS, my real employer, or Zayn Malik.

In particular, I haven’t seen the FRQs, so I can talk generally about how we score exams, but I obviously have no knowledge of the details of the FRQs — at least until the FRQs are released over the weekend.

@imthereal If the problem doesn’t specifically tell you to write getter/setter methods, then not writing them won’t be penalized.

@Potter16 Typically you lose 1 point for not using a method you wrote earlier. The other part (writing erroneous extraneous code) depends on what you wrote, but you might lose 1 more for that too. Check out CB’s scoring guidelines, they usually are the same/very similar between years.

I thought the test was fairly easy, especially the FRQ’s. MC was kind of a time crunch, but I finished and got a chance to look at all the questions I was unsure about. I used like 50 minutes for the FRQ’s and spent the rest of the time doodling. My CS class is pretty much 3/4 writing labs online and 1/4 doing FRQ’s, so I’ve had a lot of practice with code. I wish they would allot some of the FRQ time to the MC, but I’m confident in what I did this morning.

Thanks everyone! I feel better now.

I’ve seen that in the past curves for a 5 have been around 62/80 raw scores. So does that mean that theoretically someone could ace the free response and get like a 22/40 on the mc and get a 5? I didn’t ace the frq but I think I could potentially earn up to the high 30s in frq PTs but I probably got around 28-30 out of 40 on the mc so…

@Potter16 My understanding is that it’s your total points that determine your score. So, yes, it’s possible to do worse on one part (say, the MC) and better on the other part (say, the FRQs) and still get a 5. Much depends, of course, on exactly how badly you do on the first part.

The multiple choice section felt long and tedious, but not necessarily “difficult”. I finished with a few minutes to spare but in some questions I did feel like I was taking forever just trying to “run” the program and see what was the outcome.
The Free Response questions were a bit different from what I expected, so I was surprised at first but then I focused and got to working on them and to be honest they didn’t feel that difficult. Once I finished question four I looked up at the clock and I still had 55 minutes left, which was scary. It felt like too much time extra, so I went back and double checked everything.

Our teacher wasn’t preparing us at all and we didn’t realize it until it was too late.

Therefore I drew a dinosaur, a flower, and an apology letter. At the end, I also wrote song lyrics, followed by “it’s too late to apologize, but I’m sorry for wasting your time.”

I know for a fact I got a 1.

@XoXdreamerXoX It may not be much solace, but … it really doesn’t waste much of our time at all to grade a dinosaur. I’m much more sorry that you were put in that position. I hope you find a way to get some feedback to your school so that nobody else has to go through that.

Does anyone know how the scantrons work? I filled in my answers somewhat lightly because I thought I would have time to go through them.

Ugh.

Anyone have experience with this?
