I'm a rising senior at a university in the U.S. and wondering what I should apply to. My university is within the top 50 in the U.S., and I'm a double majoring in Math and International Affairs with minors in Spanish and Economics. For my mathematics coursework, I've taken proofs, linear algebra 1 and 2, graph theory, combinatorics, number theory, and abstract algebra 1 and 2. I'll be taking Real I and Differential Eq this fall as well. For econ, I've taken intro micro and macro, intermediate micro and macro, econometrics, international trade, international macro, and development economics. My current GPA is a 4.0, and I have special approval from the econ department to take phd micro and macro this fall as an undergrad. I've also been prepping for the gre and have done really well on practice tests. But, I'm aiming for top programs and I'm not sure that I have enough experience within econ to actually get in. I've had several internships related to econ and also participated in the Fed Challenge, but no actual papers or anything like that. So should I delay applying to Phds and instead apply to pre docs to give me a better chance? Or look into an RAship? Any advice would be appreciated becuase I have 0 clue what I'm doing

I might be dumb . . why isn't the answer D?

Should I apply to pre docs or a PhD?
