As mentioned, you simply need to figure out what the server is doing. Live HTTP Headers is a good way.

The following just selects Accounting courses: 

my $ua = WWW::Mechanize->new;
my $res = $ua->post( 
    'http://students.yale.edu/oci/resultWindow.jsp', 
    Content => 'term=200901&GUPgroup=A&CourseNumber=&ProgramSubject=AC
+CT&InstructorName=&timeRangeFrom=08&timeRangeTo=21&ExactWordPhrase=&y
+cRules=new&distributionGroupOperator=AND&Submit.x=145&Submit.y=7'
);
$ua->follow_link( tag => 'frame', name => 'resultFrame' );
$ua->follow_link( tag => 'frame', name => 'resultList' );
print $ua->content;

Now you can parse the html to get at the information; it's the second table in the body.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
