I recently graduated in Engineering major. I want to pursue my education in USA. I am planning to take GRE in few months. I really need to score high for scholarships as I can’t afford to pay the expenses. What study materials should I be referring in order to score high in GRE? Are there particular techniques to ace in GRE? How many days should one be studying before taking the exam? How do I improve my verbal score being a non-native speaker? Thank you .
