if i was looking at an application of someone who finished college in may and started a post-bac in august but who took no science classes as an undergraduate, it would strike me as odd. their accomplishment would be viewed by me within the context that this was a student with a 6-year rather than 4-year graduation plan. now, same student but instead of going straight to post-bac, they spend a year or two doing something tangentially related to medicine. this wouldn’t strike me as odd (and may even strike me as interesting). so i guess i revert to “it all depends”.
