title: Max number of classroom id retrieved
body: <p>I have aprox 520 classrooms archived in my account, if I try to select them with</p>
  <blockquote>
  <p>var courseList = Classroom.Courses.list({&quot;courseStates&quot;:[&quot;ARCHIVED&quot;]}).courses;</p>
  </blockquote>
  <p>I get only 300 of them. Is this normal?
  How can I select them all? Actually I'm writing a script to delete the oldest, but if I can't retrieve them, I can't delete them.</p>
