<p>Cornell doesn't provide aid for it's M.Eng. students I was able to get in with a 740Q, 640V and 5.5 AWA w/ a 3.5 GPA. However, I did undergraduate research and was a teacher's assistant for an upper division CS course. I also have about 1.5 yrs of full-time work exp. I would imagine you'd have a decent shot at Cornell and BU. </p>
<p>I think it also matters what program you apply for at CMU. I think the MSIT program is not as competitive as some of it's other graduate programs.</p>
