Hey everyone, go easy on the OP. It's a perfectly valid question...we don't know enough about this person's application to judge so quickly. Med schools are completely aware of "extracurric inflation," and I think it's pretty obvious to anyone who reads over an application when this is the case. These applications are probably the ones that would be skimmed. But some people have resumes that are just PACKED with awesome experiences! Should they pare down and not even mention some so they won't overburden admissions officers??? With the competition in this process, I would certainly hope not! I can completely understand if the extracurrics were a whole lot of nothing. But I'd also imagine that admissions officers go through such lists frequently, and if they were to come upon a really substantial list of extracurrics, that you could just tell from the descriptions were meaningful, and there was an entire PAGE of them...wouldn't the committee be impressed? In fact, wouldn't they welcome such a list?
To the OP: avoid experiences that seem like you're stretching just to add another one on & beef up the CV. If you have a large number, and they're HONESTLY very impressive, then don't eliminate some for fear of a space limit. However, if there are some that are less important...for example, it was mentioned earlier that including Dean's List, let alone listing it FOUR TIMES, might not be especially helpful...then I'd say edit and eliminate what you can.
Good luck in applying!
