I got 2(a) completely wrong.
I forgot to divide by 4 on 2(b)
I think I got ALL of 3 wrong except for my guess of less on the first part.
I forgot to find the value of c in 5(c), but I did the whole by-part thing.
I didn't show any work on 5(d).

For FRQ, I'm predicting 9,6/7,1,9,7/8,7.
And I skipped 9 of 55 on the MC.

Can I still get a 5?

I think there were only 45 MC questions which should make it a 1.2x factor to make up a 54 point composite MC score.

Wait, for 2(a), I did f(8) - f(3) / (8-3), since 5.5 is the median of those two numbers and not of 4 and 7

I thought you could only use equidistant numbers?

Alex7592

omg, nevermind

100 stupid mistakes..

I hate you self.

soslowking

what? if 8 and 3 are equidistant, why is (8-1) and (3+1) not equidistant from 5.5? both are 1.5 away from 4 and 7, right? i was a bit hesitant on that one though, can someone confirm if f(7) - f(4)/ (7-4) = 8 ppl/hour is correct?

BTW, do you think I'll get any marks if I forgot the initial condition on 4b? (so instead of passing -8 three times I only said one time, without taking f(0) = -2 into consideration. and as for the range on 6d), i put (6, infinity) b/c I forgot the initial condition (again) that f(0) = 8, any part marks? and for 5b, somehow I factored e^x (x - 3 + 1) to e^x (x - 4) [instead of x-2], so i got the interval must be greater than 4 and thus no interval; upon seeing my erred derivative, would I get part marks for relating my incorrect answer on erred info?

aii too many careless/stupid mistakes...

Thanks.

Zachsta

wait, also, are stix's answers definitively correct?

Zachsta

And does anyone have the scoring formula for AP calc?

elitespart

For multiple choice: [# correct - (.25 x # missed)] x 1.2. 54 points possible here.

Frq are 9 points each so 54 points there. Total score is out of 108.

In general:

1- 0-25
2- 26-35
3- 36-52
4- 53-63
5- 64-108

for 6c did you have to differentiate implicitly to find the coefficient of the second term in the series?

Also, how many points do you think 6c and 6d are worth?

snipez90

6c is probably 2 points (1 for 2nd derivative, 1 for answer) 6d is probably one point for the answer.

And yes you had to differentiate implicitly d/dx[(y/8)(6-y)]

intellec7

the first implicit derivative was zero, right? When I did the second implicit derivative, I got the first derivative as a factor in the second derivative, and so I got that the second derivative was also zero. I knew this was wrong so I just ignored that factor of zero and got the correct answer. Will they care, and what did I do wrong?

haha i evaluted part b of question 1

oh well. it was like some weird decimal less than 1

ihatesats2

did you guys get the bounds of 1b to be weird decimals too

elitespart

I really hope they can read my writing on 6.c). It was a mess. And yes to the post above. They were like 0.5 something and 1. something

ihatesats2

ok good(10 char)
