Dropout Rate!?!?

<p>On the MIT app, it says that 98% of freshmen return as sophomores... which means out of possibly 1000 ppl, 20 ain't showing up later.
So, does anyone know the EXACT number of dropouts over the entire undergraduate term? </p>

<p>That is, how many freshmen actually ended up being successful graduates 4 years later?</p>

<p>ECHO...echo......</p>

<p>no ones replied. means no one has dropped out.(?) or means...decide to quit life???</p>

<p>The guide books post 4-6 year graduation rates at about 92% or something like that..I think. 4 year rates are not completely valid since people stay on to complete MS with the BS...</p>
