End of July/Early August
What do you guys think the grading curve is going to be like? Similar to 2015 maybe?
@MutantsAbyss i think so, at least i hope so
I really hope the curve is high this year. I made a lot of stupid arithmetic mistakes. According to my logic during the test 10/3-1/5=-1/18 and 73=25
@athenanv13 my calculus teacher discussed the solutions that were posted on mrcalculus and she also predicted how many points each part of each free response would be worth. it seems like point awarding may be a bit generous, and the curve likewise. my teacher says that the series frq will have a very low national average as usual. not only was it a harder series question but most teachers only spend 2-3 days on series because they run out of time in the course. in addition, she anticipates that the funnel question will have a low national average (for AB and BC) because of the possibility of arithmetic errors as well as the likelihood that many students just did not know what to do.
for 3(d) on the 2016 bc frq, since they did not indicate for us to justify our answers there, do you think [-4,2] and [10,12] only would have been acceptable? i did not feel like work was necessary to support my intervals so i didn’t.
@writerzt71
Do you remember your teacher’s point prediction for the free response? I’ve figured out most of it but not all of it.
@Nazam32 : Here are her point predictions:
1: (a) 2 points: one for answer and one for the correct units.
(b) 3 points: one for demonstrating that you can do a left Riemann sum, one for getting the correct answer, and one for indicating overestimate with correct reason why.
© 2 points: one for your work, one for correct answer
(d) 2 points: one for correct answer (yes) and one for correct explanation.
2: (a) 3 points: one for finding the x-position at t=3, one for doing the work to find the x-position at t=3, and one for the y-position at t=3.
(b) 2 points: one for answer, one for indicating that you know what slope is by dy/dx = (dy/dt)/(dx/dt)
© 1 point for answer
(d) 3 points: one for correct integral from [0,1], one for correct integral from [1,2] and one for answer.
***for #2 she said it is possible that © may be worth 2pts and (d) worth 2pts depending on how they decide to assign points.
3: (a) 2 points: one for correct answer (neither) and one for correct explanation.
(b) 2 points: one for correct answer and one for correct explanation.
© 3 points: one for all your work, one for the abs. max, and one for the abs. min
(d) 2 points: one for [-4,2] and one for [10,12]. because this answer did not specify for you to justify your chosen intervals, she does not believe that there is a point tied to any explanation for this part.
4: (a) 2 points: one for d2y/dx^2 and one for doing your work (including inserting dy/dx to get d2y/dx^2)
(b) 3 points: one for correct answer, one for indicating that dy/dx = 0 at that point, and one for indicating that d2y/dx^2 < 0 at that point.
© 2 points: one for applying l’hopital’s rule and one for correct answer.
(d) 2 points: one for performing euler’s method and one for correct answer.
5: (a) 3 points: one for applying average value (the 1/10) and for having correct integral, one for correct antiderivative, and one for correct answer.
(b) 3 points: one for using area of a circle as cross section and for setting up correct integral, one for correct antiderivative, and one for correct answer.
© 3 points: two for correct work, one for correct answer.
6: (a) 3 points: one for first two terms, one for rest of terms, and one for general term.
(b) 3 points: one for correct interval of convergence, two for ratio test/work
© 1 point: one for answer
(d) 2 points: one for correctly setting up error bound, one for answer and demonstrating that it is within 0.001
@thenanv13
Ouch, our calculus teacher told us to leave the question and don’t do arithmetic
2/3 * 4/3 gives you full credit as 8/9 would.
When your teacher writes out all the FRQs and solves them, and all of your numbers seem familiar happy tears
How many points do you guys think I’ll get taken off if:
- I put ONE end of the interval as closed instead of open
- mathematical error when calculating approximation
- dividing an answer accidentally by a scalar value.
- possible lack of units
- possible decimal instead of nearest whole number approximation
Guys do you think this would be a 5? I’m really hoping for a 5, as I got a 5 in AB last year and an A in BC.
I’m being very harsh with my estimates here:
MC: 30/45
FRQ:
1: 7/9
2: 7/9
3: 8/9
4: 7/9
5: 6/9
6: 6/9
I already tried AP Pass, just wanted your guys’ opinions. Thanks 
- I don't think you'll get marked off for the brackets. My teacher says they aren't too strict on those. Max 1 point off for that.
- They usually give more value to the setup, so you'll get half/most of the credit if you had a correct setup/explanation. I would say -1.
- -1.
- Not sure about this one, since they did state to round to the nearest whole number. They might not mark you off, but if they do, it would be a point at most.
I think you did just fine…good luck!
@wormholes I would be surprised if that isn’t a 5
@writerzt71
Thanks for the point predictions. Hopefully, the predictions are right. Because at this point, I have 35/54 points on the frqs based on the answers I remember getting and the work I showed on the exam. I just hope that I get at least 30 points on the free response. For the multiple choice, it’s kind of hard to tell how I did. I’m just hoping for more than 14/45 multiple choice questions correct which is just enough to get a 4. I’m not that good at multiple choice. But at this point, I’m just hoping I passed.
@MutantsAbyss thank you, I’m really hoping for and expecting a 5!
Also anyone - I have an important question about the scoring of the exam. Sorry if it’s been asked before. So I know the AB sub score is determined by the AB questions only. Is the overall BC score determined by only the BC portions or is it both the AB and BC portions combined? Thank you!
@wormholes I’m pretty sure the BC score is both portions (AB and BC) combined
@wormholes yes the overall BC score comes from both portions combined.
@Mjain10 @writerzt71 thank you both so much for answering.
So to confirm, would this mean if someone (hypothetically of course) got a 100 on all the AB stuff on the test (around 60%) and then only a 25% on the BC stuff they would still get a 5 overall?
@wormholes I would like to think so, but I’m not completely sure
@wormholes i would like to think so because that’s over a composite score of 70. cutoff for a 5 is typically 68-70 out of 108
