<p>Reed’s 3.9 is legit (see [Reed</a> College 2007-08 Common Data Set SecC](<a href=“http://web.reed.edu/ir/cds/cds0708/cdssecc200708.html]Reed”>Reed College 2007-08 Common Data Set SecC - Institutional Research - Reed College) section C12, and <a href=“http://web.reed.edu/convocation/marthers.html)%5B/url%5D”>http://web.reed.edu/convocation/marthers.html)</a>, and it is weighted. Schools typically have their own weighting formula, but it is not necessarily public, and I don’t know Reed’s.</p>
