ap comp sci

[srawls]

so, I know a few of you have said you're taking the ap comp sci test. how do think it was? i thought it wasn't really bad, but still don't know if i'll get a 4 or 5 ( but i'm fairly certain i'll get one of them). the free response wasn't bad either, i actually kind of liked that last one on the huffman encoding, made for a simple recursive algorithm (compared to the ugly iterative solutions for all the other problems). i'm reminded of a quote "to iterate is mortal, to recurse divine" ahh, i love geeky computer quotes

Well since I don't really like computer programming and I had to take it cuz it's part of the "CAT" curriculum and all I thought it was bad. Rather, I got most of the multiple choice, probably like 30/40 but the free-response I could only get the first two for certain and then guessed on the rest... tried to get those 1/2 points n all. BTW... I only took the A not AB test.

[srawls]

ahh, ok. i took the ab test, and if you can't already tell, i love programming i enjoyed the survey at the end the best, actually. you see, my shcool doesn't offer the course so i took the test without having taken the course (i knew c++ before this year from self-study). well, when they asked 'how many hours per week does your class meet' and i answered 0, i figured i was skewing their data

oh my god, the programming A test killed me today. THe part ones werent that bad, but I only understood 2 of the part 2's they sucked! Ill be happy if i even get a 2

On this test, much like any other standardized test, I did not finish. The portions I did complete were manageable, so I think I did ok. Time will tell...

My friend took the test without taking the class too. I don't know how well he thinks he did on it yet, but we both looked at the free response questions from previous years and it seemed pretty easy. I would have taken it too but I decided I might as well wait and spend the $80 on the test after I take the class next year.

yeah i dont like aqua fish we spent 2 months on it our teachers name happens to be mr. fisher hes a stupid stupid man i think i got at least a 4 though

I think AB was alright, I was finished early with both parts. I liked their idea for Free Response Number 3 and free response problem by itself. It was a lot less enervating than Calc BC, where I just ralleyed through the Free Response.

I teach the AP CS course at my school. We just teach the AB program. My students call the case study the DAF. That's short for Dumb %%% Fish so apparently they are not impressed with it. Still they all think they got the case study questions right. We'll see.

What did you put for the last one? I'm curious because you seem sure of yourself and I am not. I put something like.

if(not at a leaf) return recall(char, left, string+"0") + recall(char, right, string+"1");
else (if char=letter) return pathsofar;
return "";

[srawls]

hmm ... from memory: (i'm shortening function name to f)

apstring f (apstring *letter, Tree* T, apstring *path_so_far) {
  apstring temp;
  if (T->Left == NULL) { //T is a leaf 
    if (T->data == letter)  
      return path_so_far;
    return "";
  }

  temp = f(letter,T->left,path_so_far + "0");
  if (temp == "")
    return f(letter,T->right,path_so_far + "1");
  return temp;
}

same thing, cool.

[srawls]

well, yours looks better than mine, but mine is more efficient. considering the ap people probably don't care anything about efficiency, i probably should have done like you and not worried about checking if the left subtree matched or not.

I aced the multiple choice part, but more then likely completely failed the 2nd part. You see, we never bothered to learn the AP classes or study the case study ( our teacher had never done ap before). It sucks because all of us in there couldve easily done all the required programming using standard c++ functions and variables. The functions they had your write were all rather simplistic and silly...they really need to redesign those tests.

For all us older people, what was the question?
