I work for large Pharma. I have a PhD (:4.0) from a top Ivy League university in Engineering. I received the best dissertation award across all Engineering departments from my university. I have published more the 10 research articles in top-tier journals. I am thinking of applying to the APD program at Mckinsey. My GRE scores aren't that great (Q800, V650). Do you think I should take the before applying? Thanks for your help!
