<p>ive listed idioms that came out in the practice tests i did and have about 50 but i see new ones everytime i take practices tests. do u guys know any good book that lists a ton of idioms that frequently come out in SAT? i know books like PR and Kaplan have some but they only have like 20, i need a whole bunch that comes out in SAT.</p>
<p>Only 1 out of like 200 WR questions directly tests an idiom, so those that you're encountering are just English language norms. If English is not your first language, I suggest you pick up a general book of idioms, but if English is your first language, I wouldn't worry about idioms, since they're tested so infrequently.</p>
