I applied to some graduate schools and I heard that what courses I have taken is an important factor for admission. But, I think the courses I have taken are a little insufficient.. the courses are Partial differential equations, Complex analysis, homological algebra, mathematical logic, Probability and random process, Numerical analysis, differential geometry, general topology and real analysis as undergraduate level. The only graduate course I took is harmonic analysis of which main topics were maximal functions, Restriction conjecture and radon transforms. I applied to graduate schools ranked top 20~40. can you please give me any opinions? How are the courses I took?
