<p>hmmm… I thought Wellesley only had [their Double-Degree Program](<a href=“http://www.wellesley.edu/USStudy/mitdoubledegree.html”>http://www.wellesley.edu/USStudy/mitdoubledegree.html</a>) which precludes a graduate level degree
irrespective of the coursework level…at MIT?</p>
<p>…I would also like to learn if it is possible do what the OP is
asking… (reading between the lines it seems the answer is No)</p>
