one on harvard, i didn't have the one on brown campus and one of my students interviewed in the unitedstates. in britain it was a little more tricky because of class . so the way you speak in the uk, that identifies your class. pretty clearly and even i as an american when i lived there, i could kind of tell someone's accent, where they came from. >> and not always to some extent. >> i happen to get around that and i can't claim this was, i was lucky so i talked to a colleague in oxford and she recommended a doctoral student who happens to be from western europe. and she was a, an officer and i did, i was a little nervous about that. at the end, it worked out well because she signaled this kind of silliness through her oxford student for being from western europe but she also obviously didn't have a class, she had no class in her voice so she had a foreign accent. and i think that in the end, after the research i felt like in the uk it would've mattered less because students that achieve at all the interviews in britain, that students said things that i wouldn't have expected they would say
