@Steve123234 i wish i remembered what the question asked though lol
Those were the numbers that were randomly generated-- not numbers removed from an integer list.
Anyone know whether the free-response has been released yet and if not, when it will be released?
They’re up now. Go ahead and start discussing!

How many marks would the part a) of the crossword question be? And how many would I get/lose if I consistently called isBlack without using Square. ?
How much would 1b and 4c be worth?
I heard that there were a lot of mistakes on the FRQ’s. (They were written poorly) If this is true then how will college board compensate for that?
Does anybody know where we can find the percentage correct on the test needed for a 5? Maybe some data from last year or something.
After reviewing the free responses again, I’m feeling that I got a minimum of 64/80 (worst case scenario).
I’m feeling good for a 5
@skstanford I’m guessing about 4 points, but you can get partial points:
I’m guessing +1 for accessing all rows and columns (for or for-each loop), +1 for using the blackSquares[][] array, and 2+ for correctly returning a boolean.
Note, isBlack() is not a function. You determine if a square is black by calling blackSquares[r][c]. If it is true, that square is black, if false, white.
The answers if anyone wants them

I can see I messed up so much lol
@nobelcollegekid where did you hear this? I guess they can make the curve bigger if it’s pretty universal that people are getting less points than last year
seeing 1b)'s answer , how much do you guys reckon it would be worth? 2 points?
General response: there’s no telling how many points will be assigned to part a/b/c of a given question. That won’t be decided for certain until the Reading (the event where all of these exams are scored).
Similarly: the lines for determining what score earns a 5, 4, etc., won’t be made until after the Reading concludes. If The Powers That Be determine that the exam was more difficult than in previous years, the cutoff lines will be adjusted lower. Conversely, if they determine that the exam was easier, the cutoff lines will be adjusted higher. The hope is that a “5” should mean the same thing from year to year.
Also will I get partial credit if I do everything else in crossword part a) except check if c== 0 and r==0?
@skstanford It all depends on how the rubric is set up. My intuition is that failing to check the border conditions is a one-point error.
lol I already forgot what I put for the FRQ’s
Yeah, so hopefully 2/3 or 3/4 ! MCQs have to be my saving grace here(don’t think I got more than a couple wrong, not sure , gotta hope). Hopefully 60/80 will net a 5 this time around, fingers crossed!
I did, 1a, 2a, 2c, 3b, 4a, and 4b completely correctly! I missed 1-2pts on 2b and 3a, and let’s not talk about 1b or 4c…
Anybody else miss the direction on the crossword puzzle question about how num should equal zero if the square has no number?
OMG I am so happy. For 1a, I transferred all the values to an arraylist and thought that it was going to be marked wrong since I didnt know if you were allowed to do that. But I did it because it was the easiest way that I thought of and turns out it is correct!!!
