问finance phd申请定位

GPA没有细算过，本科的成绩大概93/100吧，硕士成绩全A还有几门A+

推荐信打算找两个数学系的老师和一个finance的老师写，都是研究生时期的上过课的老师（之所以没有找导师写，是因为没有告诉他们我要读finance phd的打算）

研究没有和finance相关的，都是电子这个行当里的。已经发表2篇journal和3篇会议论文，在投1篇journal和1篇会议论文

我这种情况申请什么档次的学校？大概申请几所呢？

谢谢大家了

我没有考过GMAT，只有GRE，一定要考GMAT么？

The problem is, I dont even know which schools are considered top programs.

Also, should I ask the professors teaching those finance classes I have taken to write recommendation letter for me, or ask my own reasearch supervisor? I fear that my research supervisors are little known in the finance field. Moreover, should I ask a couple of math professors that have taught to write RL for me?

To your 1st question: Do some research on this board. There are information on the sticky threads. There are plenty of good schools.

To the 2nd question: My answer is yes. You do want to get RL from your professors in Finance, Math and your own area. Each should focus on different aspect of your ability and interest. Your supervisor can emphasize your proven ability on research, modeling, and so on. Your math professor can show your excellent quantitative background. As for Finance professor, use this to show why you are interested in Finance research instead of continuing your current research.
