<p>In an attempt to see what effect the con kids might have on the totals, I did a little back of the envelope calculation. Using the Boston Conservatory to get a conservatory-specific grad rate (54% in both 4 years <em>and</em> 6 years). IF Oberlin con students had similar rates, then an 81% overall graduation rate would mean that the college rate is more like 86%.</p>
