<p>According to a data set that I have seen, Harvard’s average GPA is roughly 3.9 (assuming I have remembered correctly). So, yes, your score would be high enough to be competitive. I’m not familiar with the American schooling system, so I can’t comment on prestige. To answer your other question about sport, I believe that the correct answer is: while a sport may help you to seem more ‘all-rounded’ or ‘involved with school life’, it certainly wouldn’t give you an advantage over every other exceptional applicant who can also list ‘played a sport’ on their apps. Unless you’ve achieved in the area, don’t expect it to help.</p>
