I’m an electrical engineering student .I am wondering if I can be accepted for direct phd in Nanotechnology despite my final year thesis in renewable energy? Do they accept IELTS along with GRE in US universities.Please help.
You are technially eligible for direct PhD in any course. It all depends on the University requirements. Yes, US schools accept GRE. Most of them accept TOEFL with GRE. Again, everything varies by school, so there is nothing generic.
You need to do some research on schools that fit your requirements. You probably need a very good SOP and why you want to choose Nanotechnology over renewable energy…
