The video just spoke about tangent lines for 3 minutes and dropped this question which is not even remotely related to what is being tested.
I don’t think Prepswift is ever helping people to become confident about math foundations but more like making people feel bad about being dumb.
Extremely annoyed with questions and the explainations even more complicated
This one is relatively tricky, but as far as I’m aware, there is nothing that is out of scope (and the problem is primarily related to tangents). It is important to note that PrepSwift is cumulative, so content from anywhere up to the video you covered is within scope.
Similarly, you are not expected to get every single problem right - students from a wide range of backgrounds use PrepSwift and there are a few problems sprinkled around that are meant to be challenging by design.
