I am from India and want to pursue a PhD in robotics/control systems and am not quite sure on how to start applying. I have my GRE about a month away from now. Is it okay to start contacting/emailing professors before I take the test? P.S- I have a bachelors degree. I have about a year of work experience, a year and a half research experience in a lab.

 

I would pass the GRE first. It's not a tough test, but it can be challenging.
