Williams is extremely difficult to get into without a hook, possibly as hard or harder than HYPSM (Williams takes a much bigger percentage of athletes because it is a smaller school but still has a lot of teams, so you can’t just use raw admission rates). The resume you posted is in the mix but you’ll need to make your essays really, really stand out so that you can rise above the crowd.
I’ll echo what some of the others posters said as well. Are you sure Williams is the right place for you? It can be a little more sporty than similar schools, which doesn’t seem to be your thing. Carleton, Middlebury, Bates, Haverford, Grinnell, Davidson and Hamilton come to mind as similar schools whose vibe you might like as much or more than Williams.
