ok finally i got an email of acceptance from IHEID said like this
We are pleased to inform you that the Admission Committee of the Graduate Institute, Geneva has decided to offer you admission to one of our programmes in light of your excellent academic credentials. In order to learn more about this decision, we invite you to return to the online admission module (https://campus.iheid.ch/ISAP/!formInscrs.connection?ww_c_formulaire=ADM_2014_2015&ww_c_langue=en) through which you submitted your application. If you wish to learn more about confirming our admission offer and the different enrolment steps, our admission officers will be available weekly to answer your questions on the admission and enrolment procedure, during our online information sessions for admitted students (http://graduateinstitute.ch/home/admissions/meet-us/online-information-sessions.html). The Institute's student association has created a "Meet our Current Students" initiative, which will enable you to get in touch with current students via Facebook or Email to ask them any question you may have on student life in Geneva. http://mygisa.ch/meet-students/
However I check the website, and it said "refused".
I heard only the email decision is binding, I think I should send them an email :-ss
