i was accepted to their GSP CAS program last year (obviously couldnt go for the money)....They are strong in sciences, GSP isa little different because you go there for 2 years to "catch up" with all other nyu students, and then go to CAS (college arts and science).
They have fairly good departments, i have heard there chem department is really good. In terms of help, im sure they provide more resources than the average college or university, but ultimately some of there professors are good, some arent, its like that everywhere i suppose, some places more than others.
