I'm actually happy to do a PhD with this prof) one from a course prof in Waterloo (probably the top score, not sure if the letter is strong) one from a course prof in Waterloo (a computational course with a 100% course project, scored 91. Not for biostats programs) Additional: Took tons of math heavy courses in undergraduate. Exchanged 4th year to Western U (Canada) took all kinds of grad level stats courses in Western and Waterloo with good grades (Avg.92/100) No publication. One biostats research intern. Had a best undergraduate thesis in pure math I'm sincerely worried about lack of research experience and no publication :(Programs Applying: Biostats: UNC, Havard, UMichigan, UWisconsin, UWashington Stats (haven't decided yet): UCLA, CMU (maybe??), UMichigan, UC Davis, JHU, UPenn, NCSU (maybe?) Probably aiming too high especially on stats programs. Looking for advice :)
