I am going to be blunt. This sounds like elementary schoolgirl stuff. You are a rising sophomore. Best to open your eyes and ears to many schools with wonderful potential for a wonderful education. Elite schools will look to see what you are like as a person, the problem solving you do for yourself and others, what creative juices you bring to their school. Explore ways you can make a difference. Starting multiple threads on how to get into Stanford is not going to achieve that goal.
