I think your background is good. You can reapply MFE.

You can choose the program that focus on computational finance. e.g. CMU's computational finance or Baruch's MFE, they both like applicants with good programming skill. Other choices are Tech Universities such as MIT, GT. I think they prefer the person like you.

Thank you for your reply.
I think CMU's computational finance should be the best program of MFE at US. And Baruch's MFE can make it easier to get a job on wall street.
I am taking a financial engineering course this semester, and find that there are a lot of math stuff.
What I am worrying about is whether my background in computer science is enough. I mean, do I need to strengthen my background in math. If so, what should I do? Do the courses on Coursera help? Since I will graduate at the end of this year, I can not take more courses on math or finance.

I think the admission committee may just focus on the official transcript, so Coursera won't help much. But I encourage you to take the courses on it, because it not only enhances your academic quality but also provides you somethings to talk in case there is an admission interview.

I think your math and computer science background is enough. (entry level college math is ok, calculus, linear algebra, probability theory). I recommend you to put more energy on finance. (either put as many finance courses as possible on your transcript or do more self-learning)
