Now, normally a Masters in Finance (Financial Engineering, Mathematical Finance, Computational Finance...) is highly quantitative and the requirments for being accepted into such a program are almost completely different from those of an MBA.
After floating around the website (specifically the FAQ) you can find out that the program is highly specialized in general Finance:
"we teach accounting, corporate finance, behavioral finance, etc., in addition to stochastic calculus, derivatives pricing, financial engineering, etc. "
The program also does not place much weight on work experience as the average age is 24 with not even 2 years of work experience.
Now MBA programs generally love a candidate with strong quantitaive skills; when it comes to a Masters in Finance, they wont even look at you unless you score off the charts on quant sections of the GRE or GMAT (ie: Princton GRE Quant average is 790... near perfect). One of the more disheartening things about the Princton program is that they only accept about 11% of the applicants and the program takes 2 years (normally a MS in Fin, takes only 1 year).
If you want to be considered for a top Masters in Fin. program (like Princeton), I would first get perfect scores on the GMAT and GRE Quant sections and then to set yourself above the rest score greater than 800 (out of 990) on the Subject GRE Math Test... I mean 11% is a really freaking small number!
