I am a mathematics student at Sharif University of Technology. Also, I've passed the minor course of economics in that university. My GPA is about 15.30 out of 20 and I'm planning to apply for economics. I have some questions: 1. Is a bachelor's in Mathematics going to weigh me down when applying for a master's in Economics? 2. In which universities I have a chance of getting admission with a full scholarship? 3. Is there any chance at all? because I've heard that the demand for participating in master's programs for this field is very high. What should I do?
