<p>You’re remiss to make such a sweeping generalization as the Crash Course is “not helpful” for writing the FRQs. That is patently false; there is plenty of info in the Crash Course that someone could incorporate into one’s FRQs. </p>
<p>That said, for a very high score, you will likely need more details, such as what is contained in the Essential Content. But, one can certainly write halfway decent FRQs, on most topics, if they have a strong command of the content in Crash Course.</p>
