<p>Ok. I'm having a few issues with the writing section:</p>

<h1>1 Verb tenses</h1>

<ul>
<li>I don't know when to use past perfect, present perfect, future perfect, past, present, future, etc.</li>
</ul>

<p>Examples:</p>

<p>Katherine felt that she [(A) has not had] [(B) any understanding of] the [(C) highly intricate workings] of the stock market [(D) until] her uncle took her to the New York Stock Exchange. [(E) No error]</p>

<p>Why is answer choice (A) the answer?</p>

<p>[(A) Those who] defend sequoin trees [(B) from] loggers [(C) justified] [(D) doing so] on the grounds that such trees are irreplaceable. [(E) No error]</p>

<p>Why is answer choice (C) the answer?</p>

<h1>2 Idioms</h1>

<ul>
<li>NEED HELP WITH IDIOMS (any lists?)</li>
</ul>

<p>Example: </p>

<p>[(A) Opposite to] most people I know, Annie, ..</p>

<p>Why is "Opposite to" incorrect?</p>

<p>thx</p>

<p>it's A because she stopped "not understanding". has is used for things that has not stopped. </p>

<p>* he has been dating her since sophomore year.*</p>

<p>its C because justified is the wrong tense. it should be justify.</p>

<p>The idiom is opposite from</p>

<p>search for a list on google</p>

<p>so the first sentence you would just change it to "had no" instead of "has not had"</p>
