Something we used as a tool to use was the accepted student stats that are on this site. Go through them and read them- don’t focus on all the things that you also have. Focus on what makes them stand out and what is it that you are missing and then work on that part. Everyone is going to have a high gpa. Most will have scores over 2200 SAT and SAT subjects over 700. You will see many 4’s and 5’s on AP tests, many awards and many internships. Everyone has recommendations from people that love them. Most will have some kind of “hook” and a long list of offices held, instruments played and sports they were captain of. Scrape all of that away and figure out what made them so different. That is where their acceptance was found. Not in perfect scores and over achieving because most kids that believe they will get in and apply are all of those things. Read between the lines about what makes them a special part of a bigger picture and then put that best part of you in your application. Good luck!
