Seadub is right. Since there are 8 different tracks and they are very distinctive (Environment, Finance, Entrepreneurship .... ) unlike Columbia (OR, EMS, IE, FE), you can divide the total number by 8, making each track has 30 students which is a fairly good class size.
@Souman: Congratulation with all the admits. Columbia's MFE is very prestigious, at least on top 5. It is the crown jewel of Columbia IEOR department, on par with Princeton Math Fin and Baruch MFE (though overrated). However, I would strongly suggest to go to Columbia MFE if you are not Asian because Columbia has a lot of MSOR Asian (150+) also concentrating in FE. You'd have to compete with all of them for job. Otherwise, if you are Asian, Cornell is better IMO.
Here is link to 2 reviews, one for Columbia's MFE and one for Cornell's FE
