Try Rensselaer Polytechnic Institute, I don't study there but they told me that if I applied early and had a GMAT score of more than 600 then they'd provide me a scholarship of 60%. And RPI is a pretty high ranked school. In fact there are a lots of school that provide scholarship. Devote more time to study GMAT and apply early. By applying early I mean if you plan to start MBA in 2015 then this is about right time to start applying and inquiring.
