To me it sounds like volleyball will be your main thing, and maybe calligraphy could be a secondary main thing (depending on how into it you are), and then you can round out your application with some volunteering, a few clubs, maybe a summer program or two. I can tell you that national recognition in volleyball is going to impress them the most, though – they love awards. Of course, NEVER sacrifice grades for extracurriculars – if your grades aren’t good enough they won’t even look at them. Remember, at the Ivy League level extracurriculars are mostly just a way for you to stand out from all the other national merit finalists and semi-finalists. Best of luck to you – keep up your grades and keep up with volleyball and your chances will be as good as anyone’s. Also, don’t neglect application strategy .
