This term I am a junior year Econ student in a well known European university. My current Cgpa: 3.85/4.00 My all econ courses are A except intermediate micro (A-) and math grades are A (calculus, math for econ). Only some elective courses like political science is B and B+ . Plannig to take lineer algebra&diff eq. , advance calculus this term and real analysis next year. However I am not sure that I will be able to take A from all this math courses. The question is which is more important in this case: a higher Cgpa or taking those math but passing with a-/b+? I was one term TA and one term RA as sophomore. I am planning directly going for PhD in a top school with funding because I cannot afford for master in US. How do you see my chance? Looking forward for advices.
