I am an economics major with a minor in mathematics. I have three semesters left in college, but if I took an additional semester I could complete a double major in econ and math. If completed, I would be interested in pursuing a master's in applied mathematics. My hope is that this will be broad enough to help provide diversity in options. However, I could also be interested in a master's of engineering. Help me, are these good ideas, is the extra semester worth it, I'm looking for a cost benefit analysis. My school is expensive but have no student loans because I am very lucky.
