Don't worry if you haven't heard back from Harvard yet - they take a much longer time to admit international students due to funding (this is for the PhD program, not sure about the MS). Check back late March/early April if you haven't heard from them by then
I saw three people in the results survey who were accepted by the PhD program. Any of the admits still undecided on the program?
I appear to be on some sort of waiting list - anyone else in the same boat?
