Hello gmatmr, thanks for your question.
What are the mean GMAT levels of those programs? My rule of thumb is that if you are at or near the mean, you should be fine, and if you are lower but within the middle 80% range at a school, you have a shot. Otherwise, it could be an uphill battle.
Below average extracurriculars is not a dealbreaker in itself, but your friend will then have to rely on some strong leadership experience in and out of work to mitigate that. I hope this helps.
Best of luck,
