Is Anyone Finding Contradicting Things from Khan Academy Passages?

I feel like most of what I have committed to memory have been useless from the explanations and answers given by the Khan Academy passages? It's like it's opposite of what I learned. Anybody else also feel this?

Most of KA B/BC is data-driven, so you shouldn't have to be relying on content recall too much. The information you need is in the passage. Since we don't know what you learned, we can't tell you which is right or wrong - only to rely on the passage and interpreting the data. You will get 80-90% of the questions right this way.

That's such a general statement that no one can help you.

Well, I was talking about the KA C/P section. My mistake, should have mentioned what I was referring to.

There was a passage, called "Resonance in a tube" where a question asked,

If one were to increase the temperature of the air in the tube, how would that affect the fundamental resonant frequency observed in the tube?
I answered it wouldn't change since the length of the tube determines frequency.

Correct answer was,
The fundamental resonant frequency in the tube would increase, since the speed of sound would increase in hotter air

And there was another question in "Forces on a kidney stone", https://www.khanacademy.org/test-pr...t/e/newton-s-laws-and-equilibrium---passage-1

Which of the following changes would make the kidney stone harder to pass?

I would have picked, Greater thickness of the ureter walls, since the walls are thicker, it would apply more force against the kidney stones that they would not move all. Doesn't that seem reasonable?

Oh, I would advise against using the KA C/P passages because many of them simply go beyond the scope of the MCAT (Fourier transform, complex math, etc.). It's not very good at all. The B/BC and P/S are spot-on though.

Actually, a few that I did try apart from the Fourier transform one that I did some time ago, didn't seem all that bad. The ones I did were pretty straightforward like forces acting on a kidney stone or the doppler echocardiogram. But, yeah, the P/S and B/BC are good from the few that I did do. Some of the answers for P/S look very similar. It's not even graph interpretation or anything. A lot of uncommon terms I have come across on KA were not even in Kaplan, or TPR.
