courant is definitely not nr1 math. depart. in US... where is MIT/Harvard/Princeton? finance - NYU is definitely not one of the top schools... For IBD, you have Wharton/Columbia/Chicago on the graduate level, for quant/trading you have MIT/Stanford/Princeton/Chicago. Undergraduate wise we are talking HYPSMW.
the program is okay, worse placements than berkeley and cmu. (Stanford doesnt disclose their placements, but the brand name will get you anywhere) Check the students resumés, you will not be many students going for BB. Most of them went to MM shops doing quant works - not to mention becoming a trader.
The school is overall okay and It's a good program, if you don't have other choices and don't hate coding, take it.
