SAT Writing: Idiom

<p>I always have problem with idiom errors on the SATs. </p>

<p>i.e. reject earlier offer for/of assistence? </p>

<p>It would be really nice if someone can list a few popular and tricky idiom expressions and how they are used in sentences.</p>

<p>I think it should be a “for”.</p>

<p>No, it’s “offer of assistance.” This is not an idiom: the offer was not made so that one would assist; the offer was that of assistance.</p>

<p>This may be helpful: <a href=“http://talk.collegeconfidential.com/sat-preparation/598634-idiom-list.html?highlight=idiom+list#post1061289475[/url]”>http://talk.collegeconfidential.com/sat-preparation/598634-idiom-list.html?highlight=idiom+list#post1061289475&lt;/a&gt;.&lt;/p&gt;
