I think it’s great you are a planner. Expand your list. There are literally dozens of BS schools that would give you the kind of education that will serve you for life. Also, nearly every Exeter applicant has top scores in every category and amazing EC’s as well. Many think that they’ll get in and are disappointed.
Keep doing what you are doing. Create some thing to do during Covid (there are many online activities) and when the time comes apply to a good number of schools.
Look at your list as fulfilling what you want from a school rather than relying on the name of the school.
