AP Calculus BC 2018 Thoughts

I thought AP Calculus BC was harder for the free response portion rather than multiple choice portion. I felt that the multiple choice went very smoothly for me with occasional couple questions I didn’t know definite answer to. I was struggling on the free response question about the density of the vertical sea column question. Anyone else agree?

@IvyDreamer1234 I agree, I thought there was huge difference between frq and mc in diffculty

I agree. Multiple choice calculator section was a lot easier than I expected (except for that Lagrange question towards the end). I think the plankton frq was hard, and I wasn’t able to figure out the rate of change of the distance to the origin for the polar frq.

o yea, same here… I couldn’t figure it out either… I bombed the last question too… If I get the general term wrong, I basically get everything else on that question wrong…

Do you remember what you guys got for the piecewise frq where it was asking for f(-5) and the integral of g(x) from 1 to 6 (I’m pretty sure that was the question).

I’m pretty sure I got like -13/2 for f(-5) and for g(x) from 1 to 6 I evaluated it using the actual equation.

Yeah I evaluated it using the actual equation too. I think I got 16 for the 1 to 6 integral. For f(-5) I set up an integral from 1 to x of g(x) and then added the initial condition of 3

I hope that good multiple choice score can even out the terrible free response scores and result in 5. Crossing my fingers.

Same. Since the percent of people who get a 5 is so high, I wonder if that’s because the curve is good or because most people taking the test actually know the material lol.

the plankton frq was SO hard and the maclaurin one at the end was also very tricky
