As a student in a top-tier law school, I can tell you the following:
you probably will not get in to Columbia or NYU. NYU actually has more stringent application standards than any other school in New York. As far as Fordham is concerned, you also will have a very hard time with a BTL. Fordham no longer favors BTL’s after conducting a study in which they found that the people that possessed a BTL finished in the bottom half most of the time. Also, if you do not take a writing course, or at least know how to write, going to Law School is a moot point. It is not about dissecting “Sugya’s.” It is more about putting your ideas in an effective matter on paper and analyzing them in a clear and concise manner.
