AP Calculus AB 2015 Thread

@kuftw99 For the related rates I put the same ans as you but i guessed/eliminated some other choices.

For the one about water draining into and out of the pipe, what was part C (time where water in pipe is a min)? Was the ans somewhere around 3.3 or 7 (or neither)

Was the limit and negative infinity in FRQ or MC?

What did you guys get for the last one on the calculator MC? It gave you the graph tangent to f(x) at zero and asked what must be true?

@Martin18 MC.

@stoopidfoose That sounds familiar. I don’t remember exactly what I said.

ans choice was neg 9

last question on calculator section, graph of f’(0) is = f(0)

Multiple choice @martin18 answer was ¾.

I think I got 0-2 wrong in the MC section, accounting for and stupid mistakes.

On the Free response, I thought absolutely every part was too easy except the separation of variables (I don’t see how calculus helps, I think it’s multi or something). I left C and D blank for that question, I probably should’ve put something on the paper but felt like I didn’t need to, since I’m sure I did so well on the rest of the test.

If anyone understands it lmk

@nyuad05 do you remember what choice that was? D?

Also, did anyone get 88 for the trapezoidal thing

@stoopidfoose pretty sure it was C. was that the answer though?

@nyuad05 I think I put equal but idk if its right or what choice it was

My fingers are crossed for a 5. #4 on the part 2 was brutal. On all AP tests from previous years I had been getting 5s and noticing patterns but this one the pattern wasn’t there. Did we have to use differentiable separable at all for 4?

Oh ok. Anyone get 7600 for RRAM?

And relative max for slope field frq?

I got that but I didn’t simplify. I didn’t want to make a mistake and lose credit

@stoopidfoose oh I did that wrong. I got 8 but didn’t out the integral = 0. And yes -9, and yes the negative infinity only I think. Maybe the continuous I forget

I remember 7600 as an answer for something.

For the slope field FRQ I think I said neither.

that free response went from 0-100 so quick

On Practice AP Tests I got one raw score in the 90’s and one in the 100’s. I think I probably got a raw score in the low 90’s for this one because of the No Calc MC and FRQ #4.
