I've seen some people get waitlisted/ultimately rejected at the 2 schools I interviewed simply for not having "enough clinical exposure." They had much stronger stats than I did, and both of these schools are known for their strong primary care education/"focus."
Having plenty will def. eliminate any potential doubt adcoms/admissions people may have about you if the strongest thing going for you are your stats 😛. While interviewing at both the schools, the question of what types of clinical activities I've done/how much came up as well, since I also have a lot more non-clinical/non-health related ECs than shadowing/hospital work.
Either way, I feel like having a lot of time put into anything you're clearly passionate/interested in can also somewhat compensate for that, as long as you have enough to demonstrate that you know what you're getting into.
