yeah so for 2d, I set up the integral and what not and got the answer...but when i evaluated the integral in my calculator I accidentally put in integral of 500e^whatever, instead of 550e^whatever...so instead of getting 900-something, I got 888-something

How much credit will I loose? Will I get 0 points for that part? This is depressing

Hard to say. I know back in the 1980's, the curve for a 5 on the AB test was over 80 for a 5 and in the high 60's to get a 4.

I don't know if we'll ever see those days again, though.

i am pretty sure it cannot go above 70 for a 5 on BC and likie a 75 for ab.
I mean the test was not that easy.
Compared to last year it was easier (well i took AB last year), but still it was not a cake walk.
I am happy a lil cos bc curves are a lil better

for 4c wouldn't the speed be increasing because the acceleration is positive?

No, it's decreasing. Speed is the magnitude of velocity, so the negative sign doesn't matter. That is something they always ask about on the vectors questions, since they had no vectors question they asked about it on another one.

^ my bad. Maybe not "safe" 4, but pretty sure it would be a 4. Maybe a 3 if u get real unlucky.
