To be honest, it's probably too late to help anyone else by ratting your friend out. There's no guarantee that anyone you'd help get a place was more honest than your friend either. You'd have to consider if it is really your place to compromise your friends future. Medicine is hard stuff, and she might not get in the next time. If you're cool with that then it strikes me as odd you are friends with her.
I dislike the angle everyone is taking this at though. Everybody lies? So it's fine that someone gets and offer alongside someone else who put genuine work in to develop themselves, get experience etc?
I guess as applicants we see this all as a game we are trying to play, but I think lying to the extent that you fabricate all your experiences is a bit messed up.
This could be an exaggeration though.
Edit: After re-reading, it seems like you aren't actually friends, how do you know your information is accurate?
