October Writing Section: "Would" questions

<p>In the October writing section, in the identifying sentence errors, there were about two questions with the word "would" underlined.</p>

<p>Was this the error in these sentences, or was this correct in the context of the question.</p>

<p>Also, when can you write "would" and when it is more appropriate to use "may" or "will"...or does "would" and "may" mean the same thing?</p>
