I am a grad student in Financial Economics and expect to achieve excellent grades when I graduate in August. However, my undergrad degree in Economics is not that strong, GPA 3.3. I think that this will be a huge problem when applying for a PhD in Finance at the school I want to study at (Stockholm School of Economics). On their website they say that they value applicants with also a background in a more quantitative subject as well. With my high school grades and SAT scores (95.7th percentile) I know that I can get admitted to a programme in Engineering Physics (the math programmes are not hard to get into in Sweden). This will give me the ability to get a degree in Engineering Mathematics (Bachelor) if I want. Overkill maybe but I think that this will improve my overall profile a lot, as well as give me a large edge while at the PhD programme. What would you do?
