I think it would be a big gaping hole if you failed some classes. But just passing is usually quite satisfactory. There are some med schools out there that only give pass/fail anyway. As has been stated before, grades aren't everything.
I think that a lot of times, "scholarship awards" and the like are not necessarily a great feather in anyone's cap. People get scholarship awards for everything, possibly including: Parts of their ethnic heritage, their skin color, the fact that they played tennis when they were 15, having a family member connected to a philanthropic society, living in a small town that throws out scholarships as tax benefits, owning a Borzoi, being an expert fruitcake chef, or because, paradoxically, their grades have always been low.
Honor societies are nice to have, but also are nothing incredibly special. They also don't often say too much about who you are. Certain ones like AOA or phi beta kappa indicate you have been a successful student.
I guess the question is what else you have on your application? Do you have a lot of pertinent work experience or research experience? Are your board scores high? Do you have good LORs?
They might wonder what you do with your time if you aren't volunteering or on any committees or whatever. But I think, given a solid remainder of the application, it won't make a ton of difference. They are looking for intelligent people to become pathology residents. They aren't looking for future politicians.
