Finance Management

Question: Which subject is more useful to study for a masters degree, Management, Finance or Economics?
I want a degree to complement a physics degree and is looking forward to work for the civil service or as manager in a large company in the future. Which one would be the most useful to study for this career path?
Answer: It does not really matter because when you study one, you study the other two as required courses. You may want to start in Management or Finance. Economics is more of a theoretical science and you won't it it too much in real life (unless you work for the government, etc.).
