Another broad question, I am intending to apply to bioinformatics programs in the fall; however, I have yet to write the GRE. For someone with a Master's, my research record is a little weak (no papers that I can really call my own, only some tertiary authorships). Do you think my time would be better spent honing my research interests over the next 3 months or studying for the GRE, so I can apply to more schools?
Also, I am a bit worried my list of schools is too top-heavy: UCSF, UBC, UofT, WashU. Does anyone know of any B-tier schools that do bioinformatics?
