Athletic involvement can make a big difference.
I´ve played competitive tennis all my life, won the state championship in high school, and earned a full scholarship to a Division 1 program. So far I´ve done well in the application process, and my tennis experiences might have something to do with it. My numbers are solid(3.89, 34), but maybe my sports background has made my application stand out for some schools. I think admissions committees know what it takes to be a competitive athlete - hardwork, discipline, dedication, etc. - and recognize that you are likely to have the same intensity and passion about your career. Also, I was able to use tennis stories for my essays and interviews at almost every school.
Bottom line: This med school application process is extremely competitive and there tons of many amazing candidates, so anything that can possibly separate you from the rest is huge. Keep up the tae kwon do🙂
Pineapplegirl: My only volunteer experiences were sports-related community service activites. I never thought that was a problem. As long as you have some clincial experience(shadowing, clincal research, etc.), there´s nothing wrong with teaching tennis to kids. However, if you haven´t had many clincal experiences, then it might be better to volunteer in the hospital rather than on the tennis court.
