If you haven’t yet, identify some of the key features you desire in a college – could be things like location/setting, majors, curricular style, class sizes, food and dorms, social/sports vibe, and obviously cost – and make a list of other schools that check most, if not all, of your boxes. Make sure that at least one of these schools is a safety (admit rate over 50% and your stats are at or above their 75th percentile scores/GPA). Obviously, make sure all the schools are affordable.
Not to beat a dead horse, but Stanford is extremely hard to get into. You might get in, but it’s more likely that you won’t – so make sure that you have a list of other schools that you’d enjoy attending.
