I'm looking for a university in America that has a good technology and physics departments. I have BS in physics and EE and I'm looking for a school for further studies(preferably in physics). I was eyeing Berkeley, and I called and asked. They said it was around 45.000$ per year for an international graduate student. What financial aids are available and what aids are students using who go to these schools? Can you get a scholarship purely based on grades or pay for your studies by assisting teachers and grading homework or something..??
