AB thing is just me losing my temper. I had 50 minutes worth of detailed and effective explanation of FRQs 2-6 that was just gone in front of my eyes. If you wish to see AB solutions, there are some probably online out there, but I just entirely lost motivation to cover them after the incident.
I kind of disagree with 1d. When I see the words, "The temperature of the coffee is changing", to me that means that either the temperature is increasing OR decreasing, doesn't matter which. So I interpret this as the absolute value of the first derivative, like speed not velocity. Since the second derivative is positive and the first derivative is negative, that means the rate of change of the temperature is approaching 0. Therefore I don't really think it would make sense to say "The temperature of the coffee is changing at an increasing rate", when the rate is literally approaching zero and getting slower and slower. If the temperature really was "changing at an increasing rate", then as time goes on you should expect to see larger changes in the temperature over the same time interval, which isn't happening in this case as instead, those changes in temperature are getting smaller and smaller.
D is written in a way that could have different interpretations if it is interpreted as whether the rate of which temperature is changing then iincreasing will be the answer because even though c’(t) is negative because c’’(t) > 0 the rate is increasing because c’’(t) > 0 so while the change is decreasing the rate of change is increasing , however if they mean this interpretation then it probably will be decreasing.
Also. for the alternating series error bound for the justification I just said the terms are alternating but I didn’t say decreasing in magnitude to 0. Will I still get the point???
For part c frq 6, I did the general term wrong because I put (n-1) instead of n in front. But I did use the ratio test and got the same answer of roc=6. Will I still get partial credit for it or smth??😢😢😢
@@Mr.AP5 Yeah even I was going for a perfect score, and even though I'm pretty confident that my work was correct and I'm getting a 5, I'm still leaving room for error and silly mistakes iykyk :)
Best of luck; here's hoping you get a perfect score. I'm writing the Calc AP BC exam next year directly. Any suggestions for self-study (no AP classes where I live)?
Would I get partial credit if for 1b I solved for the average value but still had the right reimmen sum and “985” written on my paper. Also for the interpretation I put “the total avg change in temp is 82.083 degrees celcius over the time period 0 mins to 12 mins” would I get partial credit for any of this cause I feel my interpretation was also slightly wrong

There’s a bit of a debate online abt that question but I agree
Yep

Not sure
wow can’t believe there was so much spanish on the test. Wish i studied preterite and imperfect! Greens and demovires theorem was also quite a shocker
If It makes yall feel better i forgot put +C for the integration by parts question on the frq.
that makes me feel worse bruh 😭

Yes, partial credit for answer will be given
I got this form, and from what I remember, I think I answered every single one correct! Best of luck on your BC Score Mr. AP! What are you predicting?
Prob a 5. I was going for a perfect score, so a 5 is like guaranteed at this point (perfect score not so much)

Do you learn all the calc ab content in calc bc?
Yes
Yes but you go through it a lot faster

Khan Academy and search for public practice tests and old FRQs

Partial for riemman sum, interpretation unlikely
@@Mr.AP5 Alr. Also would I get partial for 2d for writing that dy/dt was negative but getting the interval wrong. I put 2

@@Mr.AP5 would I at least get partial points for writing that dy/dt was decreasing
Bro somehow I missed all the points for AP Precalculus FRQ 3. It was suppposed to be the easiest FRQ ever. Also FRQ 2C was very strange.
i might be dumb but how did u already get the score
they won’t let me take bc before ab 😐
My exam was different from this, where can I find the paper I wrote? (BC)
If it is not published yet, it is unlikely your form will be published.
@@Mr.AP5where can I see which forms have been published ?
@@aproggg on collegeboard website
@@Mr.AP5 there’s only a 1 form, or am I doing something wrong ?
@@aprogggthey only really publish one form
so should I just skip ab
No AB is good preparation for BC, especially if STEM isn't your strong suit. I just lost my shit in the video.
ok
Won’t this get your scores rescinded since this is discussing AP Exam material?
You are allowed to discuss the FRQs 48 hours after the exam
