Does your HS send unhooked students outside the top 10% to schools like Williams? What does your GC think? Will you be able to visit?
You are definitely a qualified candidate, but Williams is a difficult admit for unhooked applicants. Just FYI…Bowdoin’s acceptance rate is lower than Williams and Amherst, but your ED2 strategy for Bowdoin could make sense.
I don’t think Williams’ alumni network is stronger than any of the other schools on your list. All schools will have appealing traditions. Tutorial teaching? Yes, Williams offers tutorial classes, but only 50% of the students take one, and the vast majority of those who do, don’t take a second one. IMO Williams is an academically grind-y school, and also has an athlete/non-athlete divide. Others may have different perceptions.
Have you run Williams’ net price calculator? Is the cost estimate affordable?
If you are certain Williams is your first choice, you should apply ED if it looks to be affordable. Just make sure to spend an adequate amount of time identifying match schools…do you have any of those yet? Identifying reaches is easy, and all the schools you have listed are reaches. You will also need at least one affordable safety.
