yep. I think it's something like 4.0 for A and A+, 3.7 for an A-, 3.3 for B+, 3.0 for B, 2.7 for B-. I'm not possitive, though. I found it on the website one day, and then I couldn't find it again later.
So say first semester you get 2 A's and A- and a B you take 4.0+4.0+3.7+3.0=14.7 then take 14.7/4 and you get 3.675 and thats your GPA? Then next semester you just add your next grades in with the old grades and divide by 8?
gpa does not matter. All that matters to NYU is your class-rank in relation to the prestige of your high school in conjunction with the difficulty of your classes.
although you will see "average gpa" in college rankings, the figure only becomes significant with a large sample size...high school to high school it doesnt matter, since a 3.9 in one school can be a 3.2 in another.
Just to note, class rank is an important information but it is useless in a large class size. That's why my former high school did not rank. Many teachers felt that it was unfair and inaccurate. For example, one student could have a 3.85 GPA and another student could have a 3.83 GPA, and both of might have taken same amount of rigorous classes. But in a large class (say about 600), the 3.85 student could have a class rank of 25 while the 3.83 student could have a class rank of 75....
But I agree that nyu and all colleges look at each applicant from each high school separately and does not compare them with other high schools.
