Linguistic school?

<p>I read a lot of information from many college websites and I have a few questions.</p>

<ol>
<li>It said "required courses" I really want to know this. Required courses are all subjects you must study in Master/Ph.D Degree or the subjects that you must study before when you are an undergraduate student?</li>
<li>Is there any linguistic colleges that have the introductory courses for graduate student especially Master degree? If those required courses aren't subjects thought for graduate student. </li>
<li>I heard a lot about this faculty that if you're interested in linguistics, Graduate program is better. Many people don't suggest an undergraduate program. Why?
4.Is there any colleges that have only graduate program?</li>
</ol>

<p>Actually I plan to major in Arts of English at my country but the program offers not enough linguistic courses(though it's minor program). </p>

<p>Thank you so much :)</p>
