Unfortunately it seems like no one has been willing to teach the author what mathematics is. Attempting to learn mathematics as some sort of pattern matching, which is where having large sets of questions and answers to study is useful, does not work; it isn't mathematics.
Now it's possible I'm misunderstanding the problem here: I am assuming that during lessons students have been given answers to problems worked in class, so that they can see what an answer looks like, which is probably one of the most important parts in learning introductory mathematics. Indeed, learning to validate one's own answers is not only the most important lesson in this stage of learning mathematics; it's also the only way to actually learn mathematics as it's the only way actual math gets done.
(ETA:) So I guess what I'm saying is that the author is right that no one has taught her mathematics, but as a symptom of this she doesn't even understand what form actually learning mathematics would take.
