It will do very little. It will help get you a point or so, but not much more. I am a believer that where legacies can have an advantage is their familiarity with the SA world and application process. Having someone who has been there and done that can help to guide a path early in their education path to take a challenging schedule, volunteer, scouts, sports, etc. It can help, especially if someone has expressed an interest early on that they want to follow in the family foot steps.
