I'm sure you've heard a thousand times that college admissions officers sometimes check on the social media posts of applicants. You've heard that you should be careful what you say--writers tell you not to post anything you wouldn't want your grandmother to see--but also that you should be sure to make your accomplishments clear. You've been told that colleges don't want to see photos of you with booze in your hand, but that they do want to see you're a well-rounded person with a social life. They want to see that you're engaged with your community, but that you don't get into hateful arguments or use poor judgement. You've been told all this already, and you don't need me to tell you again.
