This post is a little ridiculous. Amherst is at the top of the LAC mountain- always has been, and will likely always be. What does the top even entail? No LAC is the best at every factor. Pomona is the most endowed per student. Claremont McKenna has the lowest admit rate. Harvey Mudd has the highest SAT averages. Williams has the best general reputation. Amherst is the most diverse among its peers. Swarthmore has the highest PhD rates.
If anything, I think Williams/Amherst/Swarthmore/Pomona/Bowdoin will maintain their positions in the top 7 (which I would call the most elite group of LACs), whereas Carleton, Middlebury, and Wellesley will be replaced by CMC and Harvey Mudd due to their rise in prestige and endowment.
Amherst does lag behind in the sciences but its investment in the new science building will put it back on track in a few years.
