hey!
i was a little confused by your post, so maybe if you could clarify the situation a little bit more in another post, that would be helpful..
however, from what i got, this is what advice i would give to your friend--
i think first, ask your friend-- do you want to go into medicine and why? what is your collegue's motivation? was it from family, friends, professors, a specific experience, etc? Then tell your friend-- Hold onto that goal and motivation...
Also, another thing you should tell your collegue-- you are always going to have folks discouraging and second guessing you-- unfortunately that's how some people are sometimes, but you have to have the motivation that is way above that... i certainly had it when i went through this process, even i was doing well in my undergrad and i'm going to med school next year. if this is something your collegue really wants to do, then regardless of whatever anyone says, he/she should go for it.
And then thirdly--come up with a good plan... i would recommend talking to other people and getting a lot of advice and help. i'm not sure how AMCAS adds up gpas in the situation of your collegue, but i do that someone out there is bound to know... also know that med schools look at improvement and the upward trend... also i'm sure somewhere in your friend's personal essay, they could mention overcoming whatever difficulties, situations, and how they still have persevered and kept that motivation to go into medical field...
also, if your collegue is having trouble in classes, maybe look into getting a tutor or some other resource, so that he/she can do well for the remainder of their undergrad years.
So overall, be positive, but also be realistic as well. Get different perspectives and advice from different people, come up with a plan, and don't let what one person says get you or your friend down. 🙂
hope that helps! 🙂
