<p>^^crouch88 has already given you the information, but I will add my thoughts if you want to directly see the information here. Underline important words that are relevant to the questions, but mark the passages sparingly; you will confuse yourself when you mark all over the passages, a mistake which will cost you time and mental energy to find information in the passage.</p>
<p>OP, I have some tips. I found these patterns recurring in the wrong answer choices of the SAT, and the list is as follows:</p>
<ol>
<li><p>Veers off from the main point. The answer choice may sound right but the extra information makes the answer choice careen off from the author’s main point, argument, etc. which makes the choice a wrong answer.</p></li>
<li><p>Irrelevant. The answer choice may introduce something not mentioned in the passage[s]. If so, cross off this answer choice. It is WRONG.</p></li>
<li><p>Contradictory. The answer choice is the direct opposite of the passage, and in any case, you should cross the contradictory answer choices as well.</p></li>
</ol>
<p>I hope this information helped.</p>
