<p>Hi so I was looking through the princeton review psat book and found that it lists idioms for worried as “about, for, and by”</p>
<p>so
worried about
worried for
worried by</p>
<p>all of these sound correct but i’m finding from online sources that the only correct idiom on the psat/sat is “about”. Should I just disregard what this book says regarding “for” and “by”?</p>
